The equilibribrium distribution of water-soluble ruthenium hydrides [HRuCl(tppms)3] and [H2Ru(tppms)4] (tppms = (3-sulfonatophenyl]diphenyl-phosphane) in the reaction with H2 is governed by the pH value. As a consequence, the selectivity in the hydrogenation of cinnamaldehyde for reaction at C=C or C=O can be completely inverted by changing the pH value.
