Rhodium perfluorobutyramide (Rh2(pfm)4): a synthetically useful catalyst for olefin aziridinations

Rhodium perfluorobutyramide (Rh2(pfm)4) has been shown to catalyze the conversion of olefins to trichloroethoxysulfonyl, nosyl, and tosyl aziridines. Advantages of this aziridination procedure include the microwave-assisted preparation of the catalyst and the practical use of the alkene substrate as the limiting reagent.
