Ruthenium-catalysed oxidative coupling of vinyl derivatives and application in tandem hydrogenation

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.

CONTINUOUS DEHYDROGENATION OF 1,4-CARBOXYLATE SUBSTITUTED CYCLOHEXENES

A method which comprises contacting the cyclohexene ring containing compounds having carboxylate derivatives at the 1 and 4, and optionally the 2, positions with one or more dehydrogeoation catalysts, optionally in the presence of one or more oxidants, in a continuous flow mode under conditions such that compounds containing an aromatic ring with carboxylate derivatives at the 1. and 4 positions, and optionally the 2 position, are prepared. The invention also relates to such compounds derived from starting materials derived from renewable resources.
