An electrocatalytic system for the hydrogenation of benzaldehyde to benzyl alcohol and dibenzyl ether is described. The molybdenum hydride (C5Ph4OH)Mo(CO)3(H) (3) is shown to be the actively hydrogenating species. This hydride is demonstrated to be remarkably acid-stable, leading to a ca. 67% Faradaic efficiency for aldehyde reduction over hydrogen evolution despite strongly acidic and reducing conditions. Hydride 3 is prepared via 1-proton-2-electron reduction of cation [(C5Ph4OH)Mo(CO)3(CH3CN)][OTf] ([2][OTf]), which is generated by protonation of the Mo(0) precursor [(C5Ph4O)Mo(CO)3(L)](1).
