Photocatalytic difunctionalisations of alkenes with N-SCN sulfoximines

Abstract

Reacting N-Br sulfoximines with ammonium thiocyanate leads to unprecedented sulfur reagents, which add to vinyl arenes under photocatalysis via N-centered sulfoximidoyl radicals. As a result, 1,2-difunctionalised products are obtained, which can subsequently be derivatised taking advantage of the unique properties of the thiocyanate group.
