Abstract: A new method for the homo-coupling of aryl halides via electron-transfer oxidation of organo-cuprate Ar2Cu(I)(MgBr)2 with benzil (a 1,2-diketone) is disclosed. Various organo-cuprates were prepared from arylmagnesium bromide and half-equivalent of CuI in dry THF under nitrogen. The electron-transfer oxidation of these cuprates with benzil proceeds smoothly to produce the homo-coupled biaryls in moderate yields.
