A regioselective coupling of aliphatic ketones with alkenes has been realized by cathodic reduction. This reaction enables the formation of ketyl radicals and the activation of challenging alkenes under mild electrolysis conditions, providing an effective protocol for accessing diverse tertiary alcohols with substrate-dependent regioselectivity. The practicability of this reaction is demonstrated by

Herein, we present an efficient electrochemical method for synthesizing 2-alkyl-4-phenylalkan-2-ols through an electrochemically driven cathodic reductive coupling of the terminal and internal acetylenes with unactivated aliphatic ketones under mild conditions. The process proceeds through a ketyl radical, which then activates the aryl acetylene and causes complete reduction of the triple bond of the acetylene
