The transient radical H3Ir(PMe2Ph)3+: A bronsted acid

Electrochemical oxidation (Ep = +0.55V vs SCE) or one-electron outer-sphere oxidation of fac-H3IrP3 (P = PMe2Ph) by either Fe(bpy)33+ or Cp2Fe+ yields H2Ir(S)P3+, S = MeCN or acetone. In CH2Cl2, H4IrP3+ is a detectable product. It is concluded that these are the stoichiometric (equimolar) primary products of reaction of the transient radical [H3IrP3.+] with fac-H3IrP3. Scavenging with NEt3 or pyridine reveals that this reaction proceeds by proton transfer from H3IrP3+ and that this radical is not effectively quenched by the hydrogen atom donors iPrOH or cumene nor by the H atom acceptor [CPh3.]. It is proposed that the transient radical has the composition Ir(H2)HP3+.
