The room temperature reaction of the complex cis,trans,cis-[Ir(H)2(PPh3)2(Solv)2]PF6 (Solv is a solvent) with the imine PhCH2N=CHPh in acetone generates (with loss of H2) the orthometallated complex [Ir(H){PhCH2N=CH(o-C6H4)}(PPh3)2(Me2CO)]PF6 (3) containing a five-membered cyclometallated imine moiety. In MeOH, the reaction at an imine : Ir ratio = 1 leads to the corresponding MeOH analog of 3, while with excess imine, the mixed orthometallated imine/bezylamine complex [Ir(H){PhCH2N=CH(o-C6H4)}(PPh3)2(PhCH2NH2)]PF2 (4) is formed; the source of the coordinated amine is an Ir-promoted hydrolysis of the imine, the water likely coming from imine. Complexes 3 and 4 are fully characterized by elemental analysis, 1H and 31P{1H} NMR spectroscopy, and X-ray crystal structure analysis. [ABSTRACT FROM AUTHOR] |
