Abstract

A mild and efficient one-pot method has been developed for the synthesis of 4,5-disubstituted 3-amino-4-hydroxythiazolidine-2-thiones 1 and S,N-disubstituted 1,3,4-thiadiazole-2-thiones 9 from the reaction of aryl hydrazines and monoalkyl hydrazines, respectively, with carbon disulfide and organic halides in the presence of anhydrous potassium phosphate.
