  Synthesis and structure of sulfur and selenium capped dihydride triruthenium clusters [Ru3(CO)7(μ-H)2(μ-dppm)(μ3-E)] (E=S, Se)

  摘要：

  Reaction of [Ru-3(CO)(10)(mu-dppm)] (1) with H2S at 66 degrees C affords high yields of the sulfur-capped dihydride [Ru-3(CO)(7)(mu-H)(2)(mu-dppm)(mu(3)-S)](2), formed by oxidative-addition of both hydrogen-sulfur bonds. Hydrogenation of [Ru-3(CO)(7)(mu-dppm)(mu(3)-CO)(mu(3)-S)] (3) at 110 degrees C also gives 2 in similar yields, while hydrogenation of [Ru-3(CO)(7)(mu-dppm)(mu(3)-CO)(mu(3)-Se)] (4) affords [Ru-3(CO)(7)(mu-H)(2)(mu-dppm)(mu(3)-Se)] (5) in 85% yield. The molecular structures of 2 and 5 reveal that the diphosphine and one hydride simultaneously bridge the same ruthenium-ruthenium edge with the second hydride spanning one of the nonbridged edges. Both 2 and 5 are fluxional at room temperature being attributed to hydride migration between the non-bridged edges. Addition of HBF4 to 2 affords the cationic trihydride [Ru-3(CO)(7)(mu-H)(3)(mu-dppm)(mu(3)-S)][BF4] (6) in which the hydrides are non-fluxional due to the blocking of the free ruthenium-ruthenium edge.
