Visible-light-induced synthesis of N -disulfanyl indoles, pyrroles or carbazoles via the construction of stable S-S-N bonds.

A simple and efficient visible-light-induced approach for the formation of stable S-S-N bonds has been developed. Through these photocatalytic reactions, a series of N -disulfanyl indoles, pyrroles and carbazoles were afforded with good to excellent yields. Moreover, the gram-scale experiment has confirmed the practicability of this approach.
