Copper-catalyzed arylstannylation of arynes has been developed. This transformation enables variously substituted ortho-stannylbiaryls and teraryls to be constructed straightforwardly. An electron-deficient tin center is the key, and thus the single or dual insertion of arynes into arylstannanes is precisely controllable by simply changing the equivalence of aryne precursors.

ubiquitous Stille coupling reaction utilizes Sn-C bonds and is of great utility to organic chemists. Unlike the B-C bonds used in the Miyaura-Suzuki coupling reaction, which are readily obtained via direct borylation of C-H bonds, routes to organotin compounds via direct C-H bond functionalization are lacking. Here we report that the nickel-catalyzed reaction of fluorinatedarenes and pyridines with vinyl
