A Visible-Light-Promoted Aerobic Metal-Free C‑3 Thiocyanation of Indoles

A Visible-Light-Promoted Aerobic Metal-Free C‑3 Thiocyanation of Indoles

A simple and efficient visible-light-promoted method for the C-3 thiocyanation of indoles has been developed. The transformation uses Rose Bengal as the photocatalyst and air as the terminal oxidant. The reaction is mild, high-yielding, and environmentally benign.
