End-Functionalized Polymerization of 2-Vinylpyridine through Initial C–H Bond Activation of <i>N</i>-Heteroaromatics and Internal Alkynes by Yttrium Ene–Diamido Complexes

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.
