A general method for copper-catalyzed deprotonative dimerization of arenes by employing oxygen as the terminal oxidant has been developed. Electron-rich and electron-poor heterocycles as well as electron-poor arenes are reactive. The method is tolerant to functionalities such as nitro, cyano, dialkylamino, and ester groups.

corresponding 3-(polyfluorophenyl) prop-2-ynol derivative. Where R = N(CH3)2- and NH2- the acetylenic alcohol was not obtained; these were synthesized by the reaction of dimethylamine and ammonia with 3-(pentafluorophenyl)prop2-ynol itself. The acetylenic alcohols were converted to the corresponding polyfluorophenyl acetylenes by nickel peroxide in dioxan/aqueous NaOH. With benzene at 60° as solvent 3-(pent
