N-(4-Dimethylaminobenzylidene)anilines and N1-(4-dimethylaminophenyl)-N1,N2-diphenylformamidine reacted with tetrachloro-, tetrabromo,- and tetrafluoro-p-benzoquinones via charge-transfer complexes formation giving 2-monoarylamino-3,5,6-trihalo-p-benzoquinones and 2,5-bis(arylamino)-3,6-dihalo-p-benzoquinones. The course of the reaction leading to the formation of the products has been interpreted.
