Abstract

Di-2-pyridyl thionocarbonate, prepared from thiophosgene and 2-hydroxypyridine in the presence of triethylamine in dichloromethane, was found to be very effective for dehydration, dehydrosulfurization, and thiocarbonyl transfer reactions. Di-2-pyridyl thionocarbonate was successfully for the esterification of carboxylic acids, dehydration of aldoximes into nitriles, preparation of isothiocyanates from amines, and preparation of cyclic thionocarbonates from 1,2- and 1,3-diols.
