Chemical Communications Pub Date: 2014-05-21 DOI: 10.1039/C4CC02319F

Abstract

Enantioselective hydrogenation of tiglic acid effected by diastereomers of the general formula [(μ-H)2Ru33-S)(CO)7(μ-P–P*)] (P–P* = chiral Walphos diphosphine ligand) strongly supports catalysis by intact Ru3 clusters. A catalytic mechanism involving Ru3 clusters has been established by DFT calculations.
