摘要
Difluoromethyltri(n-butyl)ammonium chloride 1 was found to be an effective difluorocarbene reagent for O-, S-, N-, C-difluoromethylation under basic conditions. It is particularly remarkable that, when only 1.2 equivalent of reagent 1 was used, the difluoromethylated products were obtained in moderate to excellent yields.
