摘要
本文研究了超声波和相转移催化剂在Ｒｅｉｍｅｒ—Ｔｉｅｍａｎｎ反应中的应用，提出了超声波和相转移催化下Ｒｅｉｍｅｒ—Ｔｉｅｍａｎｎ反应的机理。研究结果表明：在超声波和相转移催化剂的共同作用下，二氯卡宾形成十分迅速，羟基苯甲醛产率显著提高，反应时间成倍缩短。
The effects of ultrasound and phase transfer catalysts to the behavior of Reimer-Tiemann reaction were studied and a mechanism was also proposed in this paper. The experimental results showed that the formation of dichloro carbene was relatively fast in the presence of the cooperation of ultrasound and phase transfer catalysts. Not only was the yield of hydroxybenzaldehyde remarkably increased but also the reaction time was shortened in times.
