Reactions of (η3-allyl)tetracarbonyliron cations with the highly functionalized copper reagents RCu(CN)Znl

Abstract

The addition of the highly functionalized copper reagents RCu(CN)Znl to (η³-allyl)Fe(CO)₄ cations occurs mainly at the unsubstituted allyl terminus to yield the functionalized isoprenyl derivatives; with substituents on both ends of the allyl, the regular isoprenyl adducts are isolated together with ketone products which are derived from nucleophilic additions to the carbon monoxide ligands.
