Abstract

Reaction of [Ru(η4-cisoid-2,3-dimethyl-1,3-butadiene)(η4-1,5-COD)(NCMe)] with 1,3-butadiene gives the chelate bis(allylic)ruthenium(II) complex supine,prone-[Ru(η3:η3-2,3-dimethylocta-2,6-diene-1,8-diyl)(η4-1,5-COD)] (supine,prone-2da) in 75% isolated yield as a result of cross-oxidative coupling between two different 1,3-diene units. The structure of 2da has been established unambiguously using X-ray crystallography. This provides direct evidence that the prostereogenic selective oxidative coupling at the ruthenium(0) centre occurs between the cisoid- and transoid-dienes.
