Hepta-1,6-diene and diallyl ether complexes of palladium(0) and platinum(0):a route to L–M(alkene)2 complexes containing non-activated alkenes

Abstract

With hepta-1,6-diene and diallyl ether, Pd⁰ and Pt⁰ form highly reactive homoleptic dinuclear M₂(1,6-diene)₃ complexes, which are cleaved by donors L (e.g. C₂H₄, phos-phanes, phosphites, isonitriles) to afford mononuclear derivatives L–M(1,6-diene); the X-ray structure of (Me₃P)Pd{(η²-CH₂CHCH₂)₂O} has been determined.
