  从（五甲基环戊二烯基）金属氢化物中溶剂诱导还原还原五甲基环戊二烯

  摘要：

  In acetonitrile solution, Cp*Ir(PPh3)(H)3+BF4- smoothly undergoes elimination of pentamethylcyclopentadiene (Cp*H) to yield Ir(H)2(PPh3)(NCMe)3+BF4- as the only Ir-containing product (DELTAH(double dagger) = 69.0 +/- 2.1 kJ/mol, DELTAS(double dagger) = -82.0 +/- 7.6 J/(K.mol), k(20-degrees-C) = 1.6 x 10(-4) s-1). The elimination of Cp*H did not take place in neat dichloromethane. The rate law exhibited a mixed first- and second-order dependence on the acetonitrile concentration, in accord with a mechanism involving successive acetonitrile-mediated eta5 to eta3 to eta1 ring slippage reactions, the first of which is reversible.
