摘要

A quantum chemical investigation of the Bu_4N[Fe(CO)_3(NO)]-catalyzed Cloke–Wilson rearrangement of vinyl cyclopropanes is reported. It was found that allylic CüC bond activation can proceed through a S_N2’ or S_N2- type mechanism. The application of the recently reported intrinsic bond orbital (IBO) method for all structures indicated that one Fe-N π bond is directly involved. Further analysis showed that during the reaction oxidation occurs at the NO ligand exclusively.
