Tables of 1H and 13C NMR chemical shifts have been compiled for common organic compounds
often used as reagents or found as products or contaminants in deuterated organic solvents. Building
upon the work of Gottlieb, Kotlyar, and Nudelman in the Journal of Organic Chemistry, signals for
common impurities are now reported in additional NMR solvents (tetrahydrofuran-d8, toluene-d8,
dichloromethane-d2, chlorobenzene-d5, and 2,2,2-trifluoroethanol-d3) which are frequently used in
organometallic laboratories. Chemical shifts for other organics which are often used as reagents or
internal standards or are found as products in organometallic chemistry are also reported for all the
listed solvents.
Hanging above the desk of most every chemist whose work
relies heavily on using NMR spectroscopy1 is NMR Chemical Shifts of Common Laboratory Solvents as Trace Impurities by Gottlieb, Kotlyar, and Nudelman.2 By compiling
the chemical shifts of a large number of contaminants
commonly encountered in synthetic chemistry, the publication has become an essential reference, allowing for easy
identification of known impurities in a variety of deuterated organic solvents. However, despite the utility of
Gottlieb et al.’s work,3 the chemical shifts of impurities in
a number of NMR solvents often used by organometallic
chemists were not included. Tetrahydrofuran-d8 (THF-d8),
toluene-d8, dichloromethane-d2 (CD2Cl2), chlorobenzene-d5
(C6D5Cl), and 2,2,2-trifluoroethanol-d3 (TFE-d3) are commonplace in laboratories practicing inorganic syntheses.
Therefore, we have expanded the spectral data compilation
with the inclusion of chemical shifts of common impurities
recorded in the deuterated solvents heavily employed
in our organometallic laboratories. The chemical shifts
of various gases (hydrogen, methane, ethane, propane,

ethylene, propylene, and carbon dioxide) often encountered as reagents or products in organometallic reactions,
along with organic compounds relevant to organometallic
chemists (allyl acetate, benzaldehyde, carbon disulfide,
carbon tetrachloride, 18-crown-6, cyclohexanone, diallyl
carbonate, dimethyl carbonate, dimethyl malonate, furan,
Apiezon H grease, hexamethylbenzene, hexamethyldisiloxane, imidazole, pyrrole, and pyrrolidine), have also
been added to this expanded list.
Experimental Section
All deuterated solvents were obtained commercially through
Cambridge Isotope Laboratories, Inc. NMR spectra were
recorded at 298 K using 300, 500, or 600 MHz spectrometers
(13C{1H} NMR frequencies of 75.5, 126, or 151 MHz, respectively). Adopting the previously reported strategy,2 standard
solutions of mixtures of specific impurities were used to reduce
the number of necessary individual NMR experiments. The
combinations of organic compounds were chosen in a way in
which intermolecular interactions and resonance convolution
would be minimized. Unless otherwise stated, the standard
solutions were prepared with qualitatively equal molar amounts
of the following compounds: (solution 1) acetone, dimethylformamide, ethanol, toluene; (solution 2) benzene, dimethyl sulfoxide, ethyl acetate, methanol; (solution 3) acetic acid, chloroform, diethyl ether, 2-propanol, tetrahydrofuran; (solution 4)
acetonitrile, dichloromethane, 1,4-dioxane, n-hexane, hexamethylphosphoramide (HMPA); (solution 5) 1,2-dichloroethane,
n-pentane, pyridine, hexamethylbenzene; (solution 6) tert-butyl
alcohol, 2,6-di-tert-butyl-4-methylphenol (BHT), cyclohexane,

Except for the compounds in solutions 8-10, as well as the gas samples, hexamethylbenzene, and the corrected values mentioned in the Supporting
Information, all data for the solvents CDCl3, C6D6, (CD3)2CO, (CD3)2SO, CD3CN, CD3OD, and D2O were previously reported in ref 2. b A signal for
HDO is also observed in (CD3)2SO (3.30 ppm) and (CD3)2CO (2.81 ppm), often seen as a 1:1:1 triplet (2JH,D = 1 Hz). c Not all OH signals were
observable. d In some solvents, the coupling interaction between the CH2 and the OH protons may be observed (J = 5 Hz). e In CD3CN, the OH proton
was seen as a multiplet at 2.69 ppm, as well as extra coupling to the CH2 resonance. f Apiezon brand H grease. g In some solvents, a coupling interaction
between the CH3 and the OH protons may be observed (J = 5.5 Hz). h Pyrrolidine was observed to react with (CD3)2CO.

pyrrolidine.5 In the case of TFE-d3, nitromethane was omitted
from solution 6 and run separately, since the protons of nitromethane exchange with deuterium from TFE-d3 in the presence
of triethylamine. In the case of (CD3)2CO, pyrrolidine was
omitted from solution 10, since the two compounds were observed
to react with each other. The gases used in this study included
hydrogen, methane, ethane, propane, ethylene, propylene, and
carbon dioxide.
Before examining the various standard contaminant solutions by 1H NMR spectroscopy, solvent residual signals6 and
chemical shifts for H2O7 for each NMR solvent were referenced against tetramethylsilane (TMS, δ 0 ppm) and reported.
Before collecting 13C{1H} NMR spectral data, solvent signals6
were recorded with reference to the signal of a TMS internal
standard. For D2O, 1H NMR spectra were referenced to the
methyl signal (δ 0 ppm) of sodium 3-(trimethylsilyl)propanesulfonate,8,9 and 13C{1H} NMR spectra were referenced to the
signal for the methyl group of methanol (one drop, added as an
internal standard), which was set to 49.50 ppm.2
In a typical experiment for collecting 1H NMR spectral data, a
3 μL sample of a standard contaminant solution was added to
an NMR tube containing approximately 0.4 mL of a deuterated
solvent. For 13C{1H} NMR spectral data collection, an approximately 50 μL sample of the standard contaminant solution was
added. When there was any uncertainty in the assignment of a
resonance, the solution was spiked with an additional 1-2 μL
of the impurity in question to accurately identify its chemical
shift. In cases where the chemical shifts of resonances were
highly dependent on the concentration of the impurities present, ambiguous resonances were instead resolved via gradient(4) VWR brand vacuum pump oil #19.
(5) The components of solution 10 were stable together in dilute
solution but unstable when neat mixtures were prepared. In general, it
was observed that the nitrogen-containing compounds and possibly
18-crown-6 catalyzed the hydrolysis of the carbonates, reacted directly
with them, or both. Therefore, for the purpose of storage, the solution
was partitioned into two subsolutions: (solution 10A) 18-crown-6,
imidazole, pyrrole, pyrrolidine; (solution 10B) diallyl carbonate, dimethyl carbonate, hexamethyldisiloxane. These subsolutions were
stable for long periods as neat mixtures and were combined to form
solution 10 by adding equal portions to an NMR tube containing the
desired deuterated solvent.
(6) For 1H NMR spectra, the solvent residual signals arise from the
proton of isotopomers containing one less deuterium atom than the
perdeuterated solvent: e.g., CDHCl2 in CD2Cl2. For 13C NMR spectra,
the solvent signals arise from the 13C atoms at natural abundance in the
perdeuterated solvent.
(7) The chemical shift for H2O can vary depending on the temperature, [H2O], and the solutes present: e.g., a downfield shift may be
observed in the presence of any hydrogen bond acceptors. For more
information see page 75 of ref 1.

selected heteronuclear single-quantum coherence (gs-HSQC)
and gradient-selected heteronuclear multiple-quantum coherence
(gs-HMQC) NMR spectroscopies. For the experiments involving
gases, a J. Young NMR tube containing approximately 0.4 mL of
NMR solvent was first degassed with three freeze-pump-thaw
cycles. Using a vacuum line equipped with a gas manifold, 1 atm
of the desired gas was added to the tube. Each gas was run
separately, degassing between each gas sample.
Results and Discussion
Chemical shifts for each of the impurities are reported in
the tables: 1H and 13C{1H} NMR spectral data of all substrates are presented in Tables 1 and 2, respectively. Notably,
physically larger tables, containing all the data from Tables 1
and 2 as well as the chemical shifts of additional organic
compounds, are provided in the Supporting Information.
Unless noted otherwise, coupling constants (reported in Hz)
and resonance multiplicities (abbreviated as follows: s =
singlet, d = doublet, t = triplet, q = quartet, p = pentet,
sept = septet, m = multiplet, br = broad) were observed to
be solvent-independent.
It was noted that the amount of gas dissolved in solution
gave 1H NMR signal integrations that were qualitatively
comparable to those for the solutions made with the 3 μL
additions of the liquid or solid contaminants. However, typically in order to observe signals for the gas samples by 13C{1H}
NMR spectroscopy, additional time for data collection was
required. The solubility of each gas in D2O was extremely
limited, making 13C detection impractical. Of all the gases,
methane required the most number of transients in order to
obtain an observable signal by 13C{1H} NMR spectroscopy.
In most cases, the 13C chemical shift of methane was acquired
through the use of gs-HMQC NMR spectroscopy to provide
enhanced sensitivity. In order to reflect what would be observed in typical NMR-scale experiments, 13C detection was
not pursued with isotopically enriched gases. A number of
misreported values were discovered in the years since the
original publication10 and in the preparation of this paper.
These are detailed in the Supporting Information, and the
values are now correctly listed in Tables 1 and 2.

Corrections and Comments
In the preparation of this manuscript, several errors were discovered in the
original paper1 and are reported herein. While comparing the 1H NMR spectral data
obtained in toluene-d8 to that in C6D6, it was discovered that the 1H NMR chemical shifts
for acetic acid (CH3), acetonitrile (CH3) and tert-butyl alcohol (OH) in C6D6 had each
been misreported at 1.55 ppm in the original paper; the values have now been correctly
listed as 1.52, 0.58, and 0.63 ppm, respectively. The original paper's assignments for
BHT's C(3,5) and C(4) in C6D6, (CD3)2CO, (CD3)2SO, CD3CN, and CD3OD were
reversed and are now corrected. The resonances for 1,2-dimethoxyethane (CH2) in
(CD3)2CO, silicone grease (CH3) in CDCl3, and 2-propanol (CH3) in CD3OD have been
corrected and are reported as 72.47, 1.04, and 1.15 ppm, respectively. No other
significant differences were discovered when comparing our data to that which had been
previously reported; however, we have additionally provided the OH resonance for
ethanol in C6D6 (0.50 ppm), the CH3 resonance for silicone grease in (CD3)2SO (–0.06
ppm), and replaced the “grease” entry (formerly motor oil1) with VWR vacuum pump oil
#19, which is now reported in each deuterated solvent.

(2) Except for the compounds in solutions 8–10, as well as the gas samples,
hexamethylbenzene, and the corrected values (vide supra), all data for the
solvents CDCl3, C6D6, (CD3)2CO, (CD3)2SO, CD3CN, CD3OD, and D2O were
previously reported in ref 1.
(3) A signal for HDO is also observed in (CD3)2SO (3.30 ppm) and (CD3)2CO (2.81
ppm), often seen as a 1:1:1 triplet (2JH,D = 1 Hz).
(4) Splitting pattern observed as a triplet of a non-first-order ABX pattern.
(5) Not all OH signals were observable.
(6) In some solvents, the coupling interaction between the CH2 and the OH protons may
be observed (J = 5 Hz).
(7) In CD3CN, the OH proton was seen as a multiplet at 2.69 ppm, as well as extra
coupling to the CH2 peak.
(8) Apiezon-brand H grease.
(9) In some solvents, the coupling interaction between the CH3 and the OH protons may
be observed (J = 5.5 Hz).
(10) Pyrrolidine was observed to react with the solvent (CD3)2CO.
(11) Phosphorus coupling was observed (2JPC = 3 Hz).
