By visible‐light photoredox catalysis with copper complexes, sulfoximidoyl chlorides add to terminal aryl alkynes to give the corresponding ( E )‐ β ‐chlorovinyl sulfoximines with exclusive regio‐ and stereoselectivities in high yields. Two representative products have been characterized by X‐ray crystal structure analysis. Radicals appear to be decisive intermediates. As demonstrated by two subsequent reactions, the products can be derivatized.
