摘要

h new synthesis of 1, 2, 4-thiadiazoles has been developed. N'-(Thioaroy1)-(and N'- arylthiocarbamoyl-) N, N-dimethylamidines, which were prepared in excellent yields by reactions of thioamides (and thioureas) with N, N-dimethylalkanamide dimethyl acetals, reacted with 0-(mesitylenesulfony1) hydroxylamine in dichloromethane or hydroxylamine-0- sulfonic acid in a mixture of absolute ethanol and methanol to give 1, 2, 4-thiadiazoles in ...
