A metal-free CH-CH-type coupling of arenes and alkynes, mediated by a multifunctional sulfoxide directing group, exploits nonprefunctionalized coupling partners, proceeds under mild conditions, is operationally simple, and exhibits high functional group tolerance. The products of the CH-CH coupling are highly versatile, and the metal-free process can be used for the construction and late-stage modification of important molecular scaffolds.
