## Abstract

An efficient iodine-catalyzed thio-arylation reaction of aniline was developed under electrochemical conditions. A variety of diaryl sulfide compounds can be obtained under metal-free and chemical oxidant-free conditions. The reaction features a broad substrate scope, regulation of product distribution, and scalable preparation.
