The effects of the solvent and the concentration of the reagents on the reaction path and on the results of the synthesis of biaryls from halogenoanthraquinones were investigated for the case of the reaction of 1-chloro-4-benzoylaminoanthraquinone with copper.The use of concentrated reaction mixtures and of donating aprotic dipolar solvents with copper-aryl halide ratios slightly exceeding an equimolar ratio leads to a reduction in the induction period and to an increase in the yield of the biaryls.This explained by interaction between the copmonents of the metal-aryl halide-solvent complex.
