Mao, Ting;Zhao, Liang;Huang, Yang;Lou, Yue-Guang;Yao, Qiuli;Li, Xiao-Fei;He, Chun-Yang research published 《 N-Difluoromethylation of imidazoles and pyrazoles using BrCF2PO(OEt)2 under mild condition》, the research content is summarized as follows. A simple and efficient protocol for the direct N-difluoromethylation of imidazoles and pyrazoles has been developed. The reaction makes use of com. available, non-ozone-depleting and easy handling BrCF2PO(OEt)2 as difluorocarbene precursor, and provides a cost-efficient and environmentally benign access to some difluoromethylated biol. relevant mols.
