摘要： 超声辐射在有机反应中的应用日趋广泛[1]。我们曾报道了超声辐射与相转移催化相结合产生二氯卡宾[2]和二溴卡宾[3]的方法及其与烯烃加成反应的结果。该法比单纯使用相转移催化剂[4]或超声辐射[5]更为可取。本文进一步将它用于二氯卡宾与某些含官能团化合物的反应,考察超声辐射的影响。反应是在固-液两相条件下进行的,即以粉末状氢氧化钠为碱,氯仿过量兼作溶剂。结果表明,超声辐射对各类化合物反应的影响有相当明显的差异。

Abstract: The reactions of some compounds containing functional groups, such as amines, amides, imines, alcohols, aldehydes and ketones, with dichlorocarbene under ultrasonication are reported. It is found that the reactions of those nitrogen-containing compounds can be promoted effectively by ultrasound, but of those oxygen-containing compounds the results are more complicated.

Key words: Ultrasonication, Phasc-transfer catalysis, Dichlorocarberie Compoundsc containing furictional, groups
