Abstract
Abstract In a previous paper1 it was reported that S-ethyl N-(1-tosylalkyl) thiocarbamates react with chlorine in a heterogeneous mixture of dichloromethane and aqueous sodium hydrogen carbonate to give 1-tosylalkyl isocyanates, presumably via intermediate N-(1-tosylalkyl)carbamoyl chlorides. The corresponding reaction with bromine followed a similar course. In view of these results and since little is known2–5 about the reactions of thiocarbonyl compounds with halogens, we have investigated the reactions of the readily accessible6 O-ethyl N-(1-tosylalkyl)thiocarbamates and ethyl N-(1-tosylalkyl)dithiocarbamates with anhydrous chlorine.
