  Synthesis and structural characterization of η3-allyl(α-diimine)nickel(II) complexes bearing trimethylsilyl groups

  摘要：

  A set of isomeric para- and meta-trimethylsilylphenyl ortho-substituted NN-phenyl alpha-diimine ligands [(Ar-N=C(Me)(Me)C=N-Ar) Ar = 2,6-di(4-trimethylsilylphenyl)phenyl (16); Ar = 2,6-di(3-trimethylsilylphenyl)phenyl (17)] have been synthesized through a two-step procedure. The palladium-catalysed cross-coupling reaction between 2,6-dibromophenylamine (7) and 4-trimethylsilylphenylboronic acid (8), 3-trimethylsilylphenylboronic acid (9) was used to prepare 4,4'-bis(trimethylsilyl)-[1,1';3', 1"]terphenyl-2'-ylamine (10) and 3,3'-bis(trimethylsilyl)-[1,1';3',1"]terphenyl-2'-ylamine (11). The di-1-adamantylphosphine oxide Ad(2)P(O)H (13) and di-tert-butyl-trimethylsilylanylmethylphosphine tert-BU2P-CH2-SiMe3 (14) were used for the first time as ligands for the Suzuki coupling. The condensation of 2,2,3,3-tetramethoxybutane (15) with anilines 10 and 11 afforded alpha-diimines 16 and 17. The reaction of pi-allylnickel chloride dimer (18), alpha-diimines (16), (17) and sodium tetrakis[3,5-bis(trifluoromethyl)phenyl]borate (BAF) (19) or silver hexafluoroantimonate (20) led to two sets of isomeric complexes [eta(3) -allyl(Ar-N=C(Me)-(Me)C=NAr)Ni](+) X-, [Ar=2,6-di(4-trimethylsilylphenyl)phenyl, X=BAF (3), X=SbF6 (4); Ar=2,6-di(3-trimethylsilylphenyl)phenyl, X = BAF (5), X = SbF6 (6)]. The steric repulsion of closely positioned trimethylsilyl groups in 4 caused the distortion of the nickel square planar coordination by 17.6degrees according to X-ray analysis. (C) 2004 Elsevier B.V.
