在有机合成中,经常要用到硫酸二甲酯、卤甲烷和重氮甲烷等这样一些甲基化试剂。近年来,3-甲基-1-(4-甲苯基)-三氮烯作为一种新的甲基化试剂,一些功能类似于重氮甲烷已用于许多有机合成反应中。应用 3-甲基-1-(4-甲苯基)-三氮烯可以和一些酸性物质,例如与羧酸和酚等发生反应,取代酸性氢原子,生成相应的甲酯或甲基醚,本身则变成原来的对甲苯胺。 In organic synthesis, often used to dimethyl sulfate, methyl halide and diazomethane such methylating agents. In recent years, 3-methyl-1- (4-tolyl) -triazene has been used as a new methylating agent and some functions similar to diazomethane have been used in many organic synthesis reactions. The use of 3-methyl-1- (4-tolyl) -triazene can react with acidic substances such as carboxylic acids and phenols to replace acidic hydrogen atoms to form the corresponding methyl ester or methyl ether itself It becomes the original p-toluidine.
