The reaction of direct photoinitiated iodosulfonylation of internal acetylenes with p-tolylsulfonyl iodide and its regioselectivity of the products was studied. Methods for the subsequent functionalization of β-iodovinylsulfones using cross-coupling reactions to obtain valuable and non-available compounds are proposed.
