Abstract
We successfully introduced end-capping functional groups to poly(2-vinylpyridine)s by initial introduction of the functional groups on yttrium catalysts through C-H bond activation of heteroaromatics and internal alkynes to the Y center via alkylyttrium-mediated σ-bond metathesis.
摘要
我们通过 C-H 键活化杂芳烃和内部炔烃到 Y 中心，再经由烷基钇介导的 σ 键复分解反应，成功地在聚(2-乙烯基吡啶)上引入了端基官能团。该反应最初是通过在钇催化剂上引入官能团，从而在 Y 中心上引入了官能团。
