RuH2(CO)(PPh(3))(3) was prepared in a CO2 and H-2 atmosphere from RuCl
3 and PPh(3) in the presence of alcohol and Et(3)N. Introduction of CO
into the system lead to the formation of other complexes e.g. Ru(CO)(
3)(PPh(3))(2). Addition of alkali in place of Et(3)N resulted in a dec
rease in the RuH2(CO)(PPh(3))(3) yield.
