Arylation, vinylation, and alkynylation of electron-deficient arenes and heteroarenes have been achieved by chemoselective C–H zincation followed by copper-catalyzed coupling reactions using iodonium salts. This approach offers a direct and general access to a wide scope of (hetero)biaryls as well as alkenylated and alkynylated heteroarenes under mild conditions. It is particularly useful and valuable
