摘要：

Reaction of [Ir(Me)(2)Cp*(L)] complexes (Cp* = eta(5)-C5Me5; L = PPh3, PMePh2, PMe2Ph, PMe3) with equimolar amounts of [Fe Cp-2](+) in pyridine gives methane and the corresponding cationic derivatives [Ir(Me)Cp*(L) (pyridine)](+). Reaction with an excess of NOBF4 yields methane and [Ir(Me)Cp*(L)(NO)](2+) (L=PMe3, PMe2Ph, PMePh2) or [Ir(Me)(2)Cp*(NO)](+) and [Ir(Me)Cp*(L)(2)](+) (L = PPh3) via the formation of the primary oxidation products [Ir(Me)(2)Cp*(L)](+), which have been detected by EPR spectroscopy.
