我们通过烷基钇介导的σ键复分解将杂芳烃和内部炔烃的C-H键活化到Y中心，在钇催化剂上首次引入官能团，成功地将封端官能团引入到聚(2-乙烯基吡啶)中。
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 sigma-bond metathesis.
