An efficient and convenient photocatalytic direct C-3 sulfenylation of indoles with thiophenols has been developed for the construction of 3-sulfenylations. This protocol employs thiophenols as the sulfenylating agents, inexpensive rose bengal as the photocatalyst, and shows mild conditions, readily available starting materials, high atom and step atom economy, and environmental advantages. The representative
