    Cp(CO)2(PR3)MH to Ph3C+BAr′4− [Ar′ = 3,5-bis(trifluoromethyl)phenyl] in the presence of 3-pentanone. These ketone complexes are catalyst precursors for hydrogenation of Et2CO under mild conditions (23 °C, <4 atm H2). Analogous catalytic hydrogenations are obtained from reaction of the PCy3 complexes Cp(CO)2(PCy3)MH with Ph3C+BAr′4−. The proposed mechanism involves displacement of the ketone by H2, producing
