complexes undergo conjugate addition to α,β-unsaturated carbonyl compounds to give the corresponding δ,ϵ-unsaturated carbonyl compounds in good yields. The reaction of (η3-1-or 2-trimethylsiloxyallyl) Fe(CO)2NO complexes with α,β-unsaturated ketones affords 1,6- or 1,5-diketones, respectively. (η3-1-Acetonylallyl)Fe(CO)2NO complexes also react with α,β-unsaturated carbonyl compounds to give 1,8-dicarbonyl
