  The compound CpMoH(PMe3)(3), 1, is oxidized by Ag+ in acetonitrile to the 17-electron complex [CpMoH(PMe3)(3)](+), [1](+), which is indefinitely stable at low temperature. The oxidation takes place without the observation of a silver adduct intermediate. Complex [1](+) has also been generated by ferrocenium oxidation or by anodic oxidation and characterized by EPR spectroscopy. Complex [1](+) slowly decomposes at room temperature by a second-order rate law (v = k(disp)[1(+)](2)), consistent with a disproportionation mechanism. In the presence of unoxidized I, on the other hand, the decomposition of [1](+) is faster and proceeds via a deprotonation mechanism (v = k(deprot)[1(+)][1]) with compound 1 acting as a catalyst. The ratio of the two second-order rate constants is K-deprot/K-disp = 5.8(7)). Intermediates of the disproportionation pathway, the solvent-stabilized double-oxidation products [CpMoH(S)(PMe3)(3)](2+) (S = THF, MeCN), have been isolated as stable salts with the PF6- and BF4- counterions, respectively. The acetonitrile adduct has also been characterized by X-ray crystallography. The complex [CpMoH(MeCN)(PMe3)(3)](2+) slowly transfers a proton to complex 1 to afford a 1:1 mixture of [CpMo(PMe3)(3)(MeCN)](+) and [CpMo(PMe3)(3)H-2](+) and is also slowly deprotonated by NEt3.
