| Abstract: | Oxidation of nonamethylmetallocenecarbaldehydes C5Me5MC5Me4CHO (M=Ru or Os) and the related μ-acyl clusters C5Me5MC5Me4COOs3(CO)10H with silver salts afforded η6-metallonium cations, whose structures and compositions were confirmed by the data of elemental analysis and1H,19F, and13C NMR and IR spectroscopy. The results of studies by cyclic voltammetry demonstrated that oxidation of the compounds under
study proceeded through 17-electron radical-cationic intermediates and that the μ-acyl Os3-cluster fragment is a weaker electron-withdrawing group than the CHO group.
