Abstract: We present a sp2-sp3/sp3-sp bond formation reaction through a three-component coupling strategy involving terminal alkynes, [1.1.1]propellane, and aryl thianthrenium salts that are prepared from arenes. The reaction employs a dual photo/copper catalysis system and provides… read more here.
