Summary. Some by-products of the carbazolation of di-(1-anthraquinony1)-amine in aluminium chloride-pyridine fusions rich in aluminium chloride are shown-t o result from pyridiniosubstitution and higher condensation of the 1,Z; 7,8-diphthaloyl-carbazole primarily formed.Di-( 1-anthrachinonylj-amin (1) lasst sich nach Mieg [3] in der Pyridin-Aluminium-
