intermediate organolithium complexes with chlorotrimethylsilane. The corresponding titanium complexes were synthesized in excellent yields from reactions of the trimethylsilyl derivatives with TiCl4. The titanium complexes were evaluated as styrene polymerization catalysts in toluene solution when activated by methylaluminoxane. In general, catalytic activities decreased with each additional methyl substituent
一系列多甲基取代的茚的以及allylindene,Ñ -propylindene,ñ -丁-1- enylindene,和Ñ -butylindene已经以良好的收率制备。经由中间有机锂配合物与氯代三甲基硅烷的反应,将取代的茚满转化为三甲基甲硅烷基衍生物。由三甲基甲硅烷基衍生物与TiCl 4的反应以优异的产率合成了相应的钛配合物。当被甲基铝氧烷活化时,钛络合物被评估为甲苯溶液中的苯乙烯聚合催化剂。通常,催化活性随每个另外的甲基取代基而降低。间特异性很高(90-95%)。
