The protonation of RuH2(H2)2(PCy3)2(1)(Cy = cyclohexyl) with CF3CO2H in acetone leads to the hydrido dihydrogen derivative RuH(H2)(OCOCF3)(PCy3)2(2), which reacts further in hexane to yield a very reactive RuIV dihydride, RuH2(OCOCF3)2(PCy3)2(3), a species which at room temperature is in equilibrium with the dihydrogen complex Ru(η2-H2)(OCOCF3)2(PCy3)2(4); (3)[or (4)] loses H2 in solution and reacts with cyclo-octene to give Ru(C6H9PCy2)(OCOCF3)}2(µ-O)(µ-OCOCF3)2(6).
