A process for preparing a compound I ##STR1## with A=t-butyl, aryl and R=alkyl, alkenyl, alkynyl, alkenynyl, cycloalkyl(alkyl), aryl, arylalkyl, alkyl-S-(-O)-aryl by reacting a compound III ##STR2## with a compound IV ##STR3## under the conditions of a phase-transfer reaction, is described. The process gives excellent yields and is not associated with the unpleasant odor of mercaptans.
本发明提供了一种制备化合物I的方法,其中A=t-丁基,芳基,R=烷基,烯基,炔基,烯炔基,环烷基(烷基),芳基,芳基烷基,烷基-S-(-O)-芳基,所述方法通过在相转移反应条件下将化合物III与化合物IV反应来实现。该方法产率优异,不伴有巯基的不愉快气味。
