The preparation of biaryls via oxidation of organocuprates with easily synthesized octahydro[1,4:5,8]dimethano-anthraquinone (DAQ) is described. The oxidative coupling of organocuprates using DAQ was successfully employed for the preparation of highly hindered biaryls and 9- and 10-membered macrocycles containing biaryl linkages. The oxidative reactivity of DAQ towards organocuprates is found to be similar
