J. Klein et R. Borsdorf, NMR SPECTROSCOPIC DETERMINATION OF ENANTIOMERS VIA THEIR TRIPHENYLTINDERIVATIVES - A NEW APPLICATION OF CHIRAL SOLVATING AGENTS, Fresenius' journal of analytical chemistry, 350(10-11), 1994, pp. 644-646
A method is described for the NMR determination of the enantiomeric co
mposition of chiral carboxylic acids and alcohols using their tripheny
ltin derivatives together with the chiral solvating agents quinine hyd
rochloride and phenylethylamine.
