Structure and mechanism of formation of [Fe(CO)2(PME3)2{C(CH2)–NC6H11–C-(N+HC6H11)}]BPh4–. A new type of intrtamolecular omidative addition to isocyanide co-ordinated to iron

Abstract

The structure of the title complex (1b) was resolved by X-ray diffraction methods and is supported by i.r. and ¹H n.m.r. spectal evidence; its formation proceeds via insertion of isocyanide into an iron–methyl bond, intramolecular oxidative addition to another co-ordinated isocyanide ligand, and finally iminium–enammonium rearrangement.
