Abstract

Abstract Novel rhodium-diphosphine tosylate complexes of the type [Rh (COD) L 2]+(O 3 SC 6 H 4 CH 3-p)-(L 2= diphos, prophos, buphos,(-)-DIOP) have been prepared in high yields (87-92%) by the displacement of acac ligand from Rh (COD)(acac) by p-toluenesulphonic acid in the presence of L 2. The complexes were found to be efficient hydrogenation catalysts comparable in activity to know cationic rhodium complexes. Some differences in ...
