Direct vicinal difunctionalization of π-systems has emerged as a powerful platform for constructing multiple bonds in a single synthetic operation using simple chemical feedstocks. Over the past decade, there has been exponential growth in the direct construction of successive C-S and C-I bonds using a wide variety of sulfonyl and iodide reactants through 1,2-iodosulfonylation of alkynes in a regio- and stereo-selective manner. In this review, we mainly focus on the recent developments in the preparation of β-iodovinyl sulfones and their practical applications in organic synthesis. The most promising photoredox and electrochemical transformations for synthesizing β-iodovinyl sulfones are also reviewed. The multifunctional β-iodovinyl sulfones have recently been burgeoning as versatile synthetic precursors due to the combination of vinyl iodide and vinyl sulfone moieties, essential building blocks for diverse synthetic manipulations. We hereby present the chemistry of β-iodovinyl sulfones, which can be classified into numerous sections based on the sulfonyl surrogates, and potential synthetic approaches are systematically outlined.
