Tropylium, xanthylium, and tritylium salts characterized by different stabilities differently reacted with biologically active amines. The reactions of tropylium perchlorate and tetrafluoroborate with 4-(cyclohepta-2,4,6-trien-1-yl)aniline was accompanied by hydrolysis of the N-(cyclohepta-2,4,6-trien-1-yl) derivative, the N-xanthenyl derivative underwent dehydrogenation, whereas tritylium perchlorate
