Hydrogenation of Ru(COD)(COT) (1) in the presence of 2 equiv of PCy3 leads to RuH6(PCy3)2 (2), the first hexahydride of ruthenium. This compound loses hydrogen thermally, photochemically, or in vacuo to give the dinuclear complex Ru2H6(PCy3)4. Protonation of 2 with HBF4/H2O leads to [Ru(H2O)5-(PCy3)](BF4)2, whereas reaction with ethylene produces the metalated complex RuH[C6H10P(C6H11) 2]-[P(C6H11)3](C2H 4)2,. Hydrogenation of 1 in the presence of 3 equiv of a phosphine leads to RuH4L3 [L = PCy3, P-i-Pr3, P(NEt2)3]. These complexes are shown to dissociate a phosphine in solution to give RuH4L2 and to catalyze the spontaneous H-D exchange between the phosphine protons and a deuterated solvent through a series of inter- and intramolecular C-H activation reactions.
