摘要: 在经典的 Brookhart 吡啶双亚胺后过渡金属烯烃聚合催化剂基础上, 用吡咯五元环代替吡啶六元环骨架可得到具有不同电子效应的新型吡咯亚胺配体. 通过吡咯环特殊的电子效应和位阻效应可设计出种类繁多的有别于吡啶亚胺配体的配合物. 综述了吡咯亚胺配体与前过渡金属 (Ti, Zr 等)、后过渡金属 (Fe, Co, Ni, Pd 等)、稀土金属 (Y, Ir, Lu, Nd 等) 以及其它金属 (Cu, U, Cr 等) 的配位方式、配合物的结构类型、反应性及其催化烯烃聚合反应性能.

Abstract: Nitrogen-based variations of the bis(imino)pyridine incorporated late transition metal catalysts for olefin polymerization have recently attracted attention owing to their flexible complexation to transition metals. Because steric and electronic demands can be readily introduced to the iminopyrrole unit, a wide variety of ligands and corresponding complexes have been designed and synthesized. In this contribution, we briefly review reactivity and structural features of iminopyrrolyl ligands with early transition metals Ti and Zr, late transition metals Fe, Co, Ni, and Pd, rare earth metals Y, Ir, Lu, and Nd as well as other metals such as Cu, U, and Cr and their catalytic activity for olefin polymerization.
