Carbene and Photocatalyst Catalyzed 3-acylation of Indoles for Facile Access to Indole-3-yl Aryl Ketones

3-Acyl indoles play important roles in both organic synthesis and diverse types of functional molecules. Herein, a facile nitrogen heterocyclic carbene (NHC) and photocatalyst cooperatively-catalyzed 3-acylation of indoles was disclosed. The reaction proceeded
