A simple and efficient protocol for the direct N-difluoromethylation of imidazoles and pyrazoles has been developed. The reaction makes use of commercially 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 biologically relevant molecules.

Nitration, chlorination, bromination, and iodination reactions have been investigated for pyrazole derivatives containing a difluoromethylene fragment directly on a nitrogen atom. Conditions have been found for introducing a cyano group into the nucleus of N-2-H-tetrafluoroethylpyrazole and converting it into carboxyl or tetrazole functions.
