Nucleophilic addition to tricarbonyliron complexes of α,β-unsaturated ketones and the production of 1,4-diketones

Abstract

The first examples of nucleophilic addition to tricarbonyliron complexes of α,β-unsaturated ketones are described. Addition of Grignard, organolithium, and organocuprate reagents to the tricarbonyliron complex of benzylideneacetone (1) gives 1,4-diketones. The synthesis and reactivity of the tricarbonyliron complexes of PhCHCHCOR, R = Bu (7), R = Buⁱ(8), and R = Bu^t(9) are reported.
