Herein, we first report an electrochemical methodology for the site-selective alkylation of azobenzenes with (thio)xanthenes in the absence of any transition metal catalyst or external oxidant. A variety of groups are compatible with this electrochemical alkylation, which furnishes the products in moderate to good yields.
Keywords: C–H functionalization; alkylation; azobenzenes; electrochemistry; thioxanthenes; xanthenes.
