1-(1,3-二硫戊环/二噻烷)-2-亚甲基-1-芳偶氮基丙酮类化合物的合成研究

Study on Synthesis of 1-(1,3-Dithiolan/dithian)2-ylidene-1-(phenyldiazonyl)propan-2-one

研究了二硫缩烯酮类化合物α-碳原子上的反应,以α-羰基/羧基二硫缩烯酮与芳基重氮盐作用,以较高产率获得了系列1-(1,3-二硫戊环/二噻烷)-2-亚甲基-1-芳偶氮基丙酮类化合物。该反应条件温和,操作方法简单,同时对其反应机理进行了初步探讨。

The α-Carbon atom of α-oxo/carboxyl ketene dithioacetals was studied through the reaction of α-oxo/carboxyl ketene dithioacetals with aryl diazonium salt in a simple operation,and a series of 1-（1,3-dithiolan/dithian）-2-ylidene-1-（phenyldiazonyl） propan-2-one were obtained in higher yields under mild conditions.Furthermore,the mechanism of this addition-elimination reaction was proposed preliminarily.
