Abstract

A novel and unprecedented formation of η⁴-(vinylketene)iron complexes from η⁴-(diene)iron complexes is described herein. Treatment of η⁴-(diene)iron complexes with a Lewis acid such as GaCl₃ or AlCl₃ in the presence of aromatic compounds under a CO atmosphere affords η⁴-(vinylketene)iron complexes via electrophilic aromatic substitution.
