Organotin reagents for the synthesis of π-allyl, π-cyclopentadienyl, π-indenyl, and other related π-enyl carbonyl derivatives of the transition metals

Abstract

Organotin compounds such as allyltrimethyltin, cyclopentadienyl trimethyltin, indenyltrimethyltin etc., react with a wide variety of metal carbonyl halides and other metal carbonyl compounds to afford the corresponding π-enyl metal carbonyl derivatives. In many cases conditions are very mild and yields are high, thus commending the reactions for extensive synthetic applications. The possible mechanisms of these reactions are discussed.
