以1,2-二氯四甲基二硅烷相继与环戊二烯基钠、正丁基锂和四氯化钛作用合成了标题化合物[(Me)_2Si]_2(C_5H_4)_2TiCl_2.通过元素分析、紫外光谱、~1H 核磁谱、质谱的测定,证明其结构与预见相符,并进行了 X 射线结构分析,确证了其分子结构.该晶体属于单斜晶系.测定所得键长、键角值与三个碳原子桥连的类似物(CH_2)_3(C_5H_4)_2TiCl_2中的对应值相近.
The title compound [(Me) _2Si] _2 (C_5H_4) _2TiCl_2 was synthesized by sequential reaction of 1,2-dichlorotetramethyldisilane with sodium cyclopentadienyl, n-butyllithium and titanium tetrachloride. , UV spectrum, 1H nuclear magnetic resonance spectroscopy and mass spectrometry were used to prove the structure of the crystal was in accordance with the prediction. The structure of X-ray was confirmed and its molecular structure was confirmed. The crystal belongs to monoclinic system. The corresponding values of the analog (CH_2) _3 (C_5H_4) _2TiCl_2 bridged by three carbon atoms are similar.
