Mono α‐acylation of acetone has been achieved for the first time by reacting with bench‐stable acyl azolium salts under violet‐LED light at room temperature. The intermolecular hydrogen atom transfer (HAT) from acetone to triplet state of azolium salts under violet LED irradiation resulted in thermodynamically less favourable (Z)‐α,β‐unsaturated ketones with up to 99 : 1 selectivity via C−C bond formation. This compelling protocol access the desired α‐C(sp3)−H acylation product under metal‐, ligand‐ and oxidant‐free conditions on a wide range of substrates. [ABSTRACT FROM AUTHOR] |
