N,N-Diformylanilines were prepared by the reaction of formanilide N-sodium derivatives with acetic-formic anhydride. Treatment of the N,N-diformylanilines with PCl5 and POCl3 solution led to N,N-bis(dichloromethyl)anilines, which were transformed to N,N- bis(difluoromethyl)anilines by reaction with anhydrous hydrogen fluoride in pentane solution.
N,N-二甲酰基苯胺是通过甲酰苯胺N-钠衍生物与乙酸-甲酸酐反应制备的。用PCl 5和POCl 3溶液处理N,N-二甲酰苯胺产生N,N-双(二氯甲基)苯胺,其通过与无水氟化氢在戊烷溶液中反应转化为N,N-双(二氟甲基)苯胺。
