Procedure

If, analogously to the above example, 2,5-dichloroaniline is condensed with 1,5-dichloroanthraquinone in the presence of a mixture of 0.5 part of copper powder and 0.5 part of copper-I chloride as the catalyst, instead of the copper-I iodide/picoline complex, only 12 parts of 1,5-bis-(2,5-dichloroanilino)anthraquinone are obtained, corresponding to a yield of only 23%.
