• Ruthenium-mediated selective head-to-tail dimerization of acrylic and α,β-unsaturated carbonyl compounds: generation of an acrylate-hydride complex C5Me5Ru(PCy3)(CH2CHCO2Et)H

  The ruthenium-hydride complex C5Me5Ru(PCy3)H-3 (1a) was found to be a selective catalyst precursor for the head-to-tail dimerization of acrylic and alpha,beta-unsaturated carbonyl compounds to produce bifunctional 1,5-dicarbonyl compounds. A new ruthenium species C5Me5Ru(PCy3)(CH2=CHCO2Et)H (6a) was independently generated from the substitution reaction of la with ethyl acrylate. The exclusive formation of the head-to-tail dimers suggested that, the tertiary phosphine, generated from the substitution reaction of 6a with an olefin, was the active species for the dimerization reaction.
