An efficient and convenient method was developed for the formation of S-substituted thiotriazoles through an unprecedented organometallic addition and subsequent ring-opening sequence of 3-substituted [1,2,4]triazolo[3,4-b][1,3,4]thiadiazole. The method is applicable to a wide range of substrates containing different functional groups and furnishes excellent yields of the corresponding N-unsubstituted
通过前所未有的有机金属加成和随后的 3-取代 [1,2,4] 三唑并 [3,4-b][1,3, 4]噻二唑。该方法适用于各种含有不同官能团的底物,并提供相应的 N-未取代的 3-或 5-烷基、芳基、炔基和烯基硫烷基-1,2,4-三唑产物的优异产率。
