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
