Abstract

A temperature-controlled metathesis/protonolysis takes place on group 4 amidopyridinate polymerization catalyst precursors. Unraveling this unprecedented reactivity path allowed us to highlight the importance of the metal precursor choice while preparing improved catalytic structures or studying new catalytic processes.

摘要

在第四族酰胺吡啶聚合催化剂前体上发生了温度控制的复分解/质子消除反应。揭示这条前所未有的反应途径使我们能够强调在制备改进的催化结构或研究新的催化过程时选择金属前体的重要性。
