Fluoroalkylation of Imidazoles by Hypervalent Iodonium Salts.

[摘要]：N-1H,1H-Perfluoroalkylation and regioselective C-perfluoroalkylation of imidazoles were obtained using the corresponding hypervalent iodonium salts. E.g., reaction of 1-methylimidazole with CF3CH2I(C6H5)N(SO2CF3)2 gave 96% trifluoroethylated imidazolium deriv. I.
