Biphasic catalysis with RuCl2(DMSO)(TPPMS)3

Abstract

A mononuclear RuCl2(DMSO)(TPPMS)3 complex (1) (TPPMS ¼ triphenylphosphine monosulfonate) has been synthesized. Spectroscopic analysis by i.r., u.v.–vis., 1H-, 13C-, 31P-n.m.r., cyclic voltammetry, m.s. analysis and MO calculations were in agreement with a possible octahedral structure. Biphasic (H2O/PhMe) catalytic studies have shown good olefin hydrogenation activity by the complex at moderate temperature and pressure.
