(η3-Allyl)Fe(CO)2NO 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 compounds.The mechanisms and reactivity of these conjugate addition reactions are discussed.Key words: Iron; Carbonyl; Allyl; Silicon; Nitrosyl; Ketone

The titled iron complexes derived from 3-iodo-1-trimethylsiloxypropenes and reacted with carbon nucleophiles such as NaCH(CO2Et)2 to give the corresponding nucleophile addition products in high yields.The addition occurred at the 3-position of the ligands with high regioselectivity.However, the iron complexes derived from 2-alkyl-3-iodo-1-trimethylsiloxypropenes underwent cyclization reaction with the same siloxypropenes to give dihydropyran derivatives.The diversity in the modes of reactions of the iron complexes are discussed.
