Abstract
En 中文
The direct hydroalkenylation of alkenes represents the most straightforward method for constructing C(sp2)-C(sp3) bonds. However, controlling chemo- and regioselectivity between two different alkenes remains a fundamental challenge. Herein, we developed a cobalt-catalyzed system to regioselectively ligate electron-deficient alkenes with electron-rich alkenes. The in-situ generated CoIII-H activate electron-deficient alkenes through a Markovnikov or anti-Markovnikov manner, to form linear or branched alkylcobalt species as key intermediate, which can successfully achieve regiodivergent hydroalkenylation of acrylates and analogs. The method demonstrates a broad substrate scope and functional group compatibility. Origin of regioselectivity control by the cobalt catalyst has been elucidated through mechanistic studies and density functional theory (DFT) calculations.
