N-diisopropyl-1-aminoboratabenzene-4-yl)zirconium dichloride (6a) have been prepared. X-ray crystal structures of the dimethyl derivatives of 5 and 7 show that the complexes closely resemble the corresponding ansa-zirconocenes. When activated by excess methylaluminoxane, 5a, 6a, and 7a are catalysts for the polymerization of olefins.
乙烯桥双(N,N-二异丙基-1-氨基硼烷基苯-4-基)二氯化锆(5a),二甲基甲硅烷基桥双(N,N-二异丙基-1-氨基硼基苯-4-基)二氯化锆(7a),制备二甲基亚甲基桥连的(环戊二烯基)(N,N-二异丙基-1-氨基硼烷基苯-4-基)二氯化锆(6a)。的二甲基衍生物的X射线晶体结构5和7示出的是,复合物非常类似于相应柄-zirconocenes。当被过量的甲基铝氧烷激活时,5a,6a和7a是用于烯烃聚合的催化剂。
