Thermalisation of TiCl 4 and two equivalents of a phenol in toluene is found to be the best preparative method for quantitative yields of a variety of dichlorobis(phenoxo) complexes. [TiCl 2 (OC 6 H 4 CMe 3 -4) 2 ] (1) is monomeric in benzene, a phenoxo-bridged dimer in the solid state and undergoes coordination expansion with 4,4'-dimethyl-2,2'-bipyridine (dmbipy) to give [TiCl 2 (OC 6 H 4 CMe 3 -4)

苯酚是各种二
氯双(苯氧基)配合物定量产率的最佳制备方法。[TiCl 2 (OC 6 H 4 CMe 3 -4) 2 ] (1) 在苯中是单体,苯是固态的苯氧桥二聚体,并与
4,4'-二甲基-2,2'-联吡啶发生配位膨胀(dmbipy) 得到 [TiCl 2 (OC 6 H 4 CMe 3 -4) 2 (dmbipy)] (2)。也是单体的 [TiCl 2 (OC 6 H 2 Me 3 -2,4,6) 2 ] (3) 和 [TiCl 2 (OC 6 H 3 iPr 2 -2,6) 2 ] (5) 扩展了它们的配位用 dmbipy 得到 [TiCl 2 (OC 6 H 2 Me 3 -2,4,6) 2 (dmbipy)] (4) 和 [TiCl 2 (OC 6 H 3 iPr 2 -2,6) 2 (dmbipy)] (6). 相比之下,[TiCl 2 (OC
