complexes undergo conjugateaddition to α,β-unsaturatedcarbonylcompounds to give the corresponding δ,ϵ-unsaturated carbonylcompounds 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-unsaturatedcarbonylcompounds to give 1,8-dicarbonyl

silyl peroxides was developed using readily available aldehydes as the acylating agents. This protocol provides an exceptionally useful method for the efficient and rapid synthesis of long-chain 1,6-/1,7-/1,8-diketones, especially unsymmetrical ones. This strategy also has the advantages of mild conditions, good functional group compatibility, and potential applications in the late-stage functionalization
