    • Catalysts useful for polymerizing olefins are disclosed. The catalysts comprise an activator and a bridged cyclopentadienyl complex that incorporates a monoanionic hydroxylamido or hydrazido ligand fragment. Suitable complexes have the structure: Formula (I) wherein M is a Group 4 metal; Z is a divalent linking group; X is N or O; each of R 1 and R 2 is independently C 1 -C 4 alkyl or C 6 -C 10 aryl; R 1 and R 2 can be joined together; n is 0 when X is O, and n is 1 when X is N; each Y is independently halide, alkyl, dialkylamido, aryl, or aralkyl. A modeling approach is used to identify particular valuable complexes, each of which incorporates a readily synthesized cyclopentadienyl precursor.
    • 公开了可用于聚合烯烃的催化剂。 催化剂包含活化剂和掺入单阴离子羟基酰氨基或肼基配位体片段的桥连环戊二烯基络合物。 合适的络合物具有以下结构:式(I)其中M是第4族金属; Z是二价连接基团; X为N或O; R 1和R 2各自独立地为C 1 -C 4烷基或C 6 -C 10芳基; R1和R2可以连接在一起; 当X为O时,n为0,X为N时n为1; 每个Y独立地是卤素,烷基,二烷基酰氨基,芳基或芳烷基。 使用建模方法来鉴定特定有价值的络合物,其中每一种都包含易于合成的环戊二烯基前体。
