A novel and simple strategy for the visible light-induced efficient synthesis of indol-3-yl aryl ketones from readily available arylsulfonyl chlorides and indoles with CO at room temperature was developed. This metal-free protocol has good functional group tolerance and avoids the use of transition-metal catalysts, additives, and alkaline or acidic reaction medium.
A novel palladium-catalyzed carbonylation of indoles with CO and aromatic boronic acids for the synthesis of indol-3-yl aryl ketones was developed. The reaction tolerates a wide range of functional groups and gives a variety of valuable indol-3-yl aryl ketones in high yields under mild conditions.

Abstract A visible-light-catalyzed synthesis of indol-3-yl arylketones from aryldiazonium salts, CO and indoles at room temperature was developed. This process provides a useful method for the preparation of diverse indol-3-yl arylketones from readily accessible reactants under base-free, acid-free and transition-metal-free conditions.
