介绍了一种新的结构多样的金属配合物配体（κ2-N，N）-亚氨基己内酰胺，它可以从廉价易得的起始原料中大量获得。在本报告中，该配体家族提供一类阳离子单环杂环化合物的无环脒基部分的可行替代物的能力，本文报道了脒基（CPAM）4族金属引发剂在α-烯烃活性配位聚合（LCP）和活性配位链转移聚合（LCCTP）中的应用，（η5-C5 Me 5）Hf[（R）NimcapN]（Me）2 [R =苄基（1）、CH 2（1-萘基）（2）和叔丁基[C（CH 3）3]（3）]作为丙烯的（立体选择性）LCP和LCCTP的预引发剂。
A new structurally diverse ligand for metal complexes, the (κ2-N,N)-iminocaprolactam group, that can be obtained in large bulk quantities from inexpensive and readily available starting materials, is introduced. In the present report, the ability of this family of ligands to provide a viable substitute for the acyclic amidinate moiety of a class of cationic monocyclopentadienyl, amidinate (CPAM) group 4 metal initiators for the living coordination polymerization (LCP) and living coordinative chain transfer polymerization (LCCTP) of α-olefins is documented through the synthesis of (η5-C5Me5)Hf[(R)NimcapN](Me)2 [R = benzyl (1), CH2(1-naphthyl) (2), and tert-butyl [C(CH3)3] (3)] as preinitiators for the (stereoselective) LCP and LCCTP of propene.
