摘　　要：以Si(OCH3 ) 4 和氯代环戊烷为原料 ,通过Grignard反应 ,一步法合成了二环戊基二甲氧基硅烷 ,收率为 87 8%。用IR和NMR对产品进行了表征 ,并提出了二环戊基二甲氧基硅烷的分子构型。通过丙烯聚合实验 ,考察了二环戊基二甲氧基硅烷的给电子作用 ;其结果与二苯基二甲氧基硅烷 (DDS)的作用相当 ,而催化剂活性则高于DDS。Dicyclopentyldimethoxysilane was synthesized with cyclopentaylchloride and Si(OCH_ 3)_ 4 as materials by one-step Grignard reaction,with a high yield of 87.8%.The structure of the product was characterized by IR and NMR,and the molecular configuration of dicyclopentyl-dimethoxysilane was deduced initially.The results of propylene polymerization experience showed that the properties of electron donor of dicyclopentyldimethoxysilane were equivalent to DDS,but the catalytic property was higher than that of DDS.
