The direct difunctionalization of alkenes, a cheap and abundant feedstock, is one of the most powerful and sustainable strategies for concomitant introduction of two functional groups into the π system in a single operation. In this context, vicinal azido-sulfenylation/-selenylation of alkenes has emerged as a powerful and straightforward synthetic strategy for the efficient construction of β-azido sulfides and selenides that have found application in different fields. The purpose of this review is to summarize the available literature on the synthesis of β-azido sulfides and β-azido selenides through the direct azido-sulfenylation and azido-selenylation of alkenes, respectively, focusing on the published literature from 1987 to the present.
