A general procedure for the synthesis of 3,5-dialkyl-1-amino-1H-1,2,4-triazoles from 3,5-dialkyl-4-amino-4H-1,2,4-triazoles using the 3,5-dialkyl-1,4-diamino-1,2,4-triazolium salts as intermediates is described. The parent compounds 1-amino-1H-1,2,4-triazole is not available by this method but can be prepared by electrophilic monoamination of the 1,2,4-triazolide anion.
描述了一种从3,5-二烷基-4-氨基-4H-1,2,4-三嗪合成3,5-二烷基-1-氨基-1H-1,2,4-三嗪的一般过程,使用3,5-二烷基-1,4-二氨基-1,2,4-三嗪盐作为中间体。通过这种方法无法获得母体化合物1-氨基-1H-1,2,4-三嗪,但可以通过对1,2,4-三嗪离子进行电亲核单氨化反应来制备。
