investigated. Reactions with MCl3(M = Ti, V, or Cr), VOCl3, MX4(M = Ti, Zr, Hf, or Sn; X = Cl or Br), and MCl5(M = Nb, Ta, or Mo) generally feature exchange of OPh and NMe2 groups with halide rather than complexation. In several instances, using appropriate reaction conditions, the solid adducts MX4·Ti(NMe2)4(M = Sn, X = Cl or Br; M = Zr or Hf, X = Cl), SnCl4·[Ti(cp)2(OPh)2], and ZrCl4·Ti(OPh)4 have
对于钛[Ti(CP)(OPH)方便和高收率合成3 ]和钛[Ti(CP)氯(OPH)2 ](CP =η-C 5 H ^ 5)中有所描述。混合酚盐[Ti(cp)n(OPh)4 – n ],n = 0、1或2,[TiCl 2(OPh)2 } 2 ],[Ti(cp)Cl(OPh) )2 ]和Ti(NMe 2)4的研究。与MCl 3(M = Ti,V或Cr),VOCl 3,MX 4(M = Ti,Zr,Hf或Sn; X = Cl或Br)和MCl 5反应(M = Nb,Ta或Mo)通常以卤化取代而不是络合交换OPh和NMe 2基团为特征。在某些情况下,使用适当的反应条件,固体加合物MX 4 ·Ti(NMe 2)4(M = Sn,X = Cl或Br; M = Zr或Hf,X = Cl),SnCl 4 ·[Ti(cp )2(OPh)2 ]和ZrCl 4 ·Ti(OPh)4已被隔离,并已通过分析和光谱数据充分表征。
