Protonation of transition-metal acetate and hydrido acetate complexes with fluorocarbon acids

The reactions of a series of transition-metal hydrido acetate complexes with the fluorocarbon acid H2C(SO2CF3)2 have been studied. (Ph3P)2Ru(CO)H(OAc) and (Ph3P)2Ru(CO)Cl(OAc) yield cationic, binuclear [(Ph3P)4Ru2(CO) 2(μ-X)(μ-OAc)][HC(SO2CF3)2] (X = H, Cl). Reaction of (Ph3P)3RuH(OAc) with H2C(SO2CF3)2 in toluene forms [(π-toluene)RuH(PPh3)2][HC(SO2CF 3)2]. The osmium complex (Ph3P)3OsH(OAc) provides instead [(Ph3P)3Os(η2-H2)(η 2-OAc)][HC(SO2CF3)2]·toluene in which a molecular hydrogen ligand has been characterized by its 1H spin-lattice relaxation time and JHD in the HD analogue. The crystal structure was determined but the η2-H2 ligand was not clearly resolved. Crystal data (at -63°C): P1 (triclinic), a = 14.780 (4) A?, b = 15.376 (5) A?, c = 13.854 (4) A?, α = 100.62 (2)°, β = 97.63 (2)°, γ = 77.36°, Z = 2, ρ = 1.557 g cm-3, R = 0.036. Elimination of acetic acid and formation of mer-trans-[(Ph3P)3OsH(CH3CN) 2][HC(SO2CF3)2] occurs on reaction with acetonitrile.
