The first ruthenium-catalyzed oxidative homo- and cross-coupling of exclusive vinyl derivatives giving highly valued 1,3-diene building blocks is reported. The catalytic system is based on readily available reagents and it mainly delivers the E,E isomer. This methodology also enables the synthesis of adipic acid ester derivatives in a one-pot fashion after in situ ruthenium-catalyzed hydrogenation.
On the Catalytic Dimerization of Acrylic Acid Derivatives by Palladium Complexes. IV. The Dimerization of Methyl Methacrylate

Methyl methacrylate has been dimerized to a mixture of 2.5-di(methoxycarbonyl)-hex-1-ene (1) and (E)-2.5-di(methoxycarbonyl)-hex-2-ene (2) by catalytic systems containing dichlorobis (nitrile)-palladium(II) and silver tetrafluoroborate.Codimerization experiments with methyl acrylate show a lower reactivity of methyl methacrylate.Oxidative addition of β-chloro methyl methacrylate to tetrakis(triphenylphosphine)palladium(0) gave β-palladio methyl methacrylates (8,9) suitable for model investigations of the catalytic reaction.A proposal is given for a mechanism via Pd(IV) intermediates.
