摘要：

Hydrogen transfer from the formic acid/triethylamine (5:2) azeotrope to alpha,beta-unsaturated carboxylic acids is effectively catalyzed by ruthenium complexes of general formula [Ru(acac-F6)(eta-3 - C3H5)(diphosphine)]. If a chiral diphosphine is employed, the saturated acids are obtained in up to 93% ee, the most active and selective catalyst being formed with BINAP.
