自Doering发现溴仿在叔丁醇钾作用下产生二溴卡宾的方法以来,人们对此作了不少改进.其中Makosza的相转移催化方法,因其反应条件温和而被广为采用.但该法后处理不够方便,产率一般.近年来,有机声化学反应的研究进展十分迅速.前文我们报道了在超声波作用下产生三员环卡宾和二氯卡宾的方法.本文将讨论用超声波辐射和相转移催化相结合产生二溴卡宾的结果. Since Doering discovered that bromoform produced dibromocarbene under the action of potassium tert-butoxide, many improvements have been made in this regard, among which Makosza’s phase-transfer catalysis has been widely adopted because of its mild reaction conditions. In recent years, the research progress of organic acoustic chemical reaction is very rapid.We have reported above the method of producing three-member cyclic carbene and dichlorocaine under the action of ultrasonic wave.This article will discuss the use of ultrasonic radiation and Phase transfer catalysis combined to produce dibromocarbene results.
