Resumen:
The reactions of [Ir(PMe3)(4)]Cl (1) with a variety of substrates (acetonitrile, p-aminobenzonitrile, p-cyanophenol) containing a nitrile group were examined. Cleavage of the X-H bonds occurred selectively over the coordination of the CN moiety in those substrates, and compounds derived from the corresponding X-H (X = C, N, O) oxidative addition reaction, namely, cis-[IrH(CH2CN)(PMe3)(4)]Cl (2), cis-[IrD(CD2CN)(PMe3)(4)]Cl (3), cis- [IrH(p-NHC6H4CN)(PMe3)(4)]Cl (4), and cis-[IrH(p-OC6H4CN)(PMe3)(4)]Cl (6), were obtained. X-ray diffraction studies have confirmed the structures of 3 and 4. In the case of 6, the compound trans-[IrClH(PMe3)(4)][p-OC6H4CN] (5b), resulting from exchange of Cl and p-OC6H4CN anions between inner and outer sphere, was also formed, and the solid-state structure (5b center dot HOC6H4CN), obtained by X-ray diffraction, contained the hydrogen-bonded NCC6H4O center dot center dot center dot H center dot center dot center dot OC6H4CN anion. The salt [Ir(PMe3)(4)][BPh
