摘要： 通过1,3-二(1-茚基)四甲基二硅氧烷的双锂盐与TiCl4·2THF反应制得硅桥联二(1-茚基)钛化合物(Me2SiOSiMe2)[Ind]2TiCl2(1),对其催化氢化得到相应的四氢茚基化合物(Me2SiOSiMe2)[IndH4]2TiCl2(2).对化合物1和2的单晶进行了X射线衍射结构分析,它们的晶体都属单斜晶系,P21/n空间群.

Abstract: The chiral ansa-metallocene derivative sila-bridged bis(1-indenyl)titanium dichloride(Me2SiOSiMe2)[Ind]2TiCl2(1)has been prepared by the reaction of the dilithium salt of 1,3-bis(1-indenyl) tetramethyl disiloxane with TiCl4·2THF.After catalytic hydrogenation,1 has been converted to the corresponding tetrahydroindenyl complex (Me2SiOSiMe2)·[IndH4]2TiCl2(2).The crystal structures of 1 and 2 have been determined by X-ray diffraction analysis.Both the crystals belong to monolinic, space group P21/n.For 1,a=1.0546(4)nm,b=1.3773(7)nm,c=1. 5493(5) nm;β=99.05(3)°,V=2.222(1)nm3,Z=4,Dc=1.43 g/cm3,R=0.033.For 2, a=1.0911(2)nm,b=1.3815 (3)nm,c=1.5886(2)nm;β=101. 39 (1)°,V=2.347(1)nm3,Z=4,Dc=1.378g/m3,R=0.053.

Key words: Sila-bridged bis(1-indenyl)titanium dichloride, X-ray diffraction analysis, Ansa-metallocene
