  名称：

  Intramolecular CH activation and oxidative addition reactions of iridium complexes containing arylamines with bulky substituents on n itrogen; X-ray structures of [IrI(C6H4CH2NEt2-2-C,C)] and [IrIII(C6H4CH2Net(CHMe)-2-C,N,C′)I(cod)] (cod = cycloocta-1,-5-diene)

  摘要：

  Square-planar iridium(I) complexes [Ir(C(6)H(4)CH(2)NRR') (cod)] (R = R' = Et; R = Me, R' = t-Bu; cod = cycloocta-1,5-diene) containing C,N-chelating arylamine ligands have been synthesized and characterized by NMR spectroscopy. An X-ray diffraction study of [Ir(C(6)H(4)CH(2)NEt(2)-2-C,N) (cod)] shows a weak agostic interaction between the d(8) metal center and a methyl H atom of one ethyl group. An oxidative addition reaction of this complex with MeI affords an Ir(III) complex [Ir(C(6)H(4)CH(2)NEt(CHMe)-2-C,N,C')I(cod)] which results from an intramolecular methylene C-H activation process. This latter complex has been characterized with 2D NMR techniques and an X-ray diffraction study. The reactivity of the new iridium(I) complexes as well as [Ir(C(6)H(4)CH(2)NMe(2)-2-C,N) (cod)], [Ir(1-C(10)H(6)NMe(2)-8-C,N) (cod)] and [Ir(C6H4CH2N(Me)CH(2)CH(2)NMe(2)-2-C,N) (cod)] towards H-2 is reported; the different products obtained are discussed with reference to reaction pathways influenced by the steric bulk on the nitrogen donor atom. Crystals of [Ir(C(6)H(4)CH(2)NEt(2)-2-C,N)(cod)] are triclinic, space group P (1) over bar with unit-cell dimensions a = 9.154(1), b = 9.992(1), c = 10.846(1) Angstrom, (alpha = 93.46(1), beta = 113.03(1), gamma = 109.84(1)degrees, Z = 2, final R = 0.0234, wR = 0.0295 for 3465 reflections with I>2.5 sigma(I) and 197 parameters. Crystals of [Ir(C(6)H(4)CH(2)NEt(CHMe>-2-C,N,C')I(cod)] are triclinic, space group P (1) over bar with dimensions a = 7.591(1), b = 11.406(1), c = 13.511(1) Angstrom, alpha = 65.63(1), beta = 88.34(1), gamma = 83.29(1)degrees, Z = 2, final R = 0.0319, wR = 0.0402 for 4236 reflections with I>2.5 sigma(I) and 228 parameters.
