End-Functionalized Polymerization of 2-Vinylpyridine through Initial C-H Bond Activation of N-Heteroaromatics and Internal Alkynes by Yttrium Ene-Diamido Complexes
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.
