Ruthenium(<scp>ii</scp>)-catalyzed switchable C3-alkylation versus alkenylation with acrylates of 2-pyridylbenzofurans via C–H bond activation

Abstract

We documented an interesting observation of ruthenium(<sc>ii</sc>)-catalyzed benzofuran C–H activation and subsequent functionalization with acrylates that reveals that a simple base can switch the process from alkylation to alkenylation.
