Conversion of α,β-unsaturated ketone complexes into α,β-unsaturated ketene complexes
Abstract
Treatment of (α,β-unsaturated ketone)tricarbonyliron(0) complexes with organolithium reagents under an atmosphere of carbon monoxide gave products which were identified as (α,β-unsaturated ketene)tricarbonyliron(0) complexes based on a crystal structure analysis of [PhCHCHC(Me)C–O](CO)3Fe(0)(2), the product obtained form (PhCHCHCOMe)(CO)3Fe(0)(1).
