钼 Mo(NR)(CHCMe2Ph)(DFTO)2 (R = 2,6-i-Pr2C6H3, 2,6-Me2C6H3, C6F5, 1-金刚烷基；DFTO = 2,6-(C6F5)2C6H3O) 和单芳基氧化物单吡咯 (MAP) 配合物的双 DFTO 亚烷基配合物Mo(NR)(CHCMe2Ph)(Me2Pyr)(OAr) (Me2Pyr = 2,5-二甲基吡咯烷；R = C6F5，OAr = DFTO，2,6-二甲苯酚 (HMTO)；R = 2,6-Me2C6H3，OAr = DFTO) 已以良好的产率制备。将二甲氧基降冰片二烯 (DCMNBD) 添加到双DFTO 络合物中，产生具有顺式全同立构结构的聚合物。 DCMNBD 通过 Mo(NC6F5)(CHCMe2Ph)(Me2Pyr)(HMTO) 聚合得到包含预期的顺式间同立构结构的聚合物，但 DCMNBD 通过 Mo(NR)(CHCMe2Ph)(Me2Pyr)(DFTO) (R = C6F5, 2,6-Me2C6H3) 聚合生成具有顺式全同立构结构的聚合物，这是首次观察到使用 MAP 引发剂制备的顺式全同立构聚合物。降冰片烯聚合得到高立构顺式聚NBE。乙烯与 Mo(NC6F5)(CHCMe2Ph)(DFTO)2 的加成导致形成 Mo...
The bisDFTO alkylidene complexes of molybdenum Mo(NR)(CHCMe2Ph)(DFTO)2 (R = 2,6-i-Pr2C6H3, 2,6-Me2C6H3, C6F5, 1-adamantyl; DFTO = 2,6-(C6F5)2C6H3O) and monoaryloxide monopyrrolide (MAP) complexes Mo(NR)(CHCMe2Ph)(Me2Pyr)(OAr) (Me2Pyr = 2,5-dimethylpyrrolide; R = C6F5, OAr = DFTO, 2,6-dimesitylphenoxide (HMTO); R = 2,6-Me2C6H3, OAr = DFTO) have been prepared in good yields. Addition of dicarbomethoxynorbornadiene (DCMNBD) to bisDFTO complexes yielded polymers that have a cis,isotactic structure. Polymerization of DCMNBD by Mo(NC6F5)(CHCMe2Ph)(Me2Pyr)(HMTO) gives a polymer that contains the expected cis,syndiotactic structure, but polymerization of DCMNBD by Mo(NR)(CHCMe2Ph)(Me2Pyr)(DFTO) (R = C6F5, 2,6-Me2C6H3) generates a polymer that has a cis,isotactic structure, the first observation of a cis,isotactic polymer prepared employing a MAP initiator. Norbornene is polymerized to give what is proposed to be highly tactic cis-polyNBE. Addition of ethylene to Mo(NC6F5)(CHCMe2Ph)(DFTO)2 leads to formation of Mo...
