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.

2010年4月16日 · 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-d 8, toluene-d 8, dichloromethane-d 2, chlorobenzene-d 5, and 2,2,2-trifluoroethanol-d 3) which are frequently used in organometallic laboratories. Chemical ...

NMR Chemical Shifts of Emerging Green Solvents, Acids, and Bases for Facile Trace Impurity Analysis. ACS Sustainable Chemistry & Engineering 2023, 11 (14) , 5696-5725. https://doi.org/10.1021/acssuschemeng.3c00244

These tables can support you in identifying and separating NMR signals of impurities that might originate from residual solvents or from your reaction apparatus. Here we present the NMR shifts of the most commonly used solvents and impurities in organic synthesis measured in the 7 most frequently used deuterated solvents.

2016年2月19日 · Since their publication in 1997, the tables of chemical shifts found in NMR Chemical Shifts of Common Laboratory Solvents as Trace Impurities by Gottlieb, Kotlyar, and Nudelman have been an invaluable resource for synthetic chemists to identify residual solvents, e.g., Et 2 O or THF, in research samples.

The article provides corrections and updated NMR chemical shift values for various trace impurities found in common laboratory solvents, including toluene and deuterated solvents. Key misreported values from prior research are rectified, ensuring accurate data for researchers in organometallic chemistry.

1997年11月1日 · In the course of the routine use of NMR as an aid for organic chemistry, a day-to-day problem is the identification of signals deriving from common contaminants (water, solvents, stabilizers,...
