Abstract
A simple and efficient strategy for the synthesis of 3-sulfenyl and 3-selenyl indoles via a visible light-induced tandem cyclization of 2-alkynylanilines with disulfides (diselenides) was developed. The reaction generated the corresponding products in good yields at room temperature under transition metal-free and photocatalyst-free conditions.
