Methylation of arenes is one of the versatile approaches to achieve structural modification in organic and medicinal chemistry. Installation of a methyl group onto an aromatic ring can lead to significant improvenent of the physical properties and biological activity of this molecule, thusly the effect oftentimes is called the“magic methyl effect”. During the past few years, visible-light-induced photocatalysis has emerged as a powerful tool for the development of efficient transformations in organic synthesis. Compared to traditional radical mediated reactions, the use of visible light as energy input is more environmentally benign. Recently, a series of aryl methylation reactions enabled by visible light photoredox catalysis have been reported and applied in the synthesis of pharmaceutically-interested products. In this review, the recent progress of visible-light-induced aryl methylation reactions is briefly summaried, with discussions of different reaction pathways.

Key words: methylation, radical-mediated reaction, methyl radical, photoredox catalysis
