The kinetics of hydride transfer from a series of metal hydrides (MH) to Ph3C+BF4- (producing Ph3CH and M---FBF3) have been studied by stopped-flow methods in CH2Cl2 solution. Second-order rate constants at 25 °C span 5 orders of magnitude in kinetic hydricity, ranging from k = 5.0 × 101 M-1 s-1 for HMn(CO)5 to k = 4.6 ×106 M-1s-1 for trans-HMo(CO)2(PMe3)Cp.
