Bis(cyclopentadienyl)titanium(IV)/zirconium(IV) complexes, [Cp2M(J-R)] [where M = Ti or Zr and H2J-R is a Jäger type ligand with bridging group R (ethylene, o-phenylene or 4-methyl-o-phenylene], have been synthesized. The subsequent condensations of the complexes (R = o-phenylene) with o-phenylenediamine have also been studied, which cause ring closure and the formation of cyclic complexes. All these
双(环戊二烯基)钛(IV)/锆(IV)配合物,[Cp 2 M(JR)] [其中M = Ti或Zr,H 2 J-R是带有桥基R(J,乙烯,邻-亚苯基或-)的Jäger型配体合成了[ 4-甲基-邻苯撑],随后研究了配合物(R =邻苯撑)与邻苯二胺的缩合反应,这些反应会导致闭环和环状配合物的形成,所有这些衍生物都是通过元素分析,电导,磁矩和光谱(电子,IR,1 HNMR)的数据。1这些配合物的1 H NMR谱表明环戊二烯基环绕金属环轴快速旋转。提出了复合物的可能结构。
