Abstract

Metalhydrides such as $Cp(CO)_{2}(L)MH$ (L = t-butylisocyanide and 2,6-dimethylphenylisocyanide M = Mo and W) have been synthesized and used for ionic hydrogenation of the carbonyl groups in the presence of triflic acid. When these complexes have also used as catalyst precursors for hydrogenation of 3-pentanone under mild conditions ($23^{\circ}C,\;<4.1\;atm H_{2}$). The turnover rates were very slow, with the fastest initial rate of about 2 turnovers per 1 day for the [$Cp(CO)_{2}(ArNC)Mo][BA_{r}^{F}_{4}$] system.
