Abstract

Chlorination is a widely used strategy at the industrial level. Chlorinated products represent indispensable building blocks in synthetic chemistry. Here, we report the synthesis of benzyl chlorides and alpha-chloro alkyl arenes, mediated by visible light, starting from variously substituted toluenes and N,N-dichloroacetamide as a chlorinating reagent. This methodology is a valid alternative to the syntheses previously reported in the literature. It is a metal-free process and does not involve the use of additives or radical initiators.
