The palladium‐catalyzed addition of indoles to nitriles affords 3‐acylindoles. The reaction proceeds with high selectivity, wide substrate scope, broadly available starting materials, and an operationally simple procedure. Combination with the palladium‐catalyzed intramolecular oxidative coupling of 3‐indolylarylketone gives access to indenoindolones in a one‐pot synthesis.

A visible-light-catalyzed synthesis of 3-acylindoles from simple indoles and α-oxo acids at room temperature has been discovered. This method offers rapid access to 3-acylindoles through C–C and C–H bond activation.

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.
