Abstract

In aqueous solutions, [RuCl2(TPPMS)2]2 (TPPMS=3-sulfonatophenyldiphenylphosphine) catalyzes the exchange between H2 and D2O or between D2 and H2O with high efficiency (up to 1252 turnovers per hour) under mild conditions (298K, 2MPa H2). The exchange rate strongly depends on the solution pH. Similar H/D exchange is observed with the water soluble tertiary phosphine complexes [RhCl(TPPMS)3], [RhCl(TPPTS)3] and [RuCl2(PTA)4] as catalysts (TPPTS=tris(3-sulfonatophenyl)phosphine, PTA=1,3,5-triaza-7-phosphadamantane) which, however, show lower activity.
