This work describes an electrochemicalammoniumcation enabled hydropyridylation of ketone-activated alkenes under metal- and exogenous reductant free conditions giving access to β-pyridyl ketones, through dual proton-coupled electron transfer and radical cross-coupling. It features a broad substrate scope and allows a gram-scale synthesis. Ammonium chloride plays various roles in this transformation

Efficient hydrogenation of electron‐deficient internal olefins and alkynes access to saturate ketone with CH3OH as a single hydrogen donor under electrochemical conditions has been successfully developed. This hydrogenation strategy can be used to convert electron‐deficient internal olefins and alkynes to saturate ketone under electrochemical conditions with exogenous‐reductant and a metal catalyst
