Convenient iodine-mediated aminoselenation of alkenes using benzotriazoles as nitrogen sources

Abstract

A new and convenient procedure mediated by I₂ was developed for the preparation of aminoselenides bearing the benzotriazole structure using alkenes, diselenides, and benzotriazoles. In this protocol, molecular I₂ first reacts with diselenides to form active electrophilic selenium species, following an electrophilic addition to afford the corresponding aminoselenides. This aminoselenation of alkenes requires mild reaction conditions and is a simple procedure, and it provides the products with high regioselectivity and in good yields, which extends the synthetic application of molecular iodine in organic synthesis.
