Metal‐Free Photoinduced Transformation of Aryl Halides and Diketones into Aryl Ketones

Abstract

The acylation of aryl halides to prepare aryl ketones without metal catalyst represents an important yet challenging topic towards more sustainable ketone synthesis. Herein, we describe a simple and efficient metal‐free protocol for the acylation of aryl halides with diketone under the irradiation of light utilizing N ‐methylpiperidine as base under an air atmosphere. This reaction can tolerate a wide range of functional groups and the corresponding ketones can be obtained in modest to good yields.
