Oxidative coupling of 4a,9-diaza-1,2,4a,9a-tetrahydro-9H-fluorene with primary amines and ammonia in the presence of MnO2 gives the corresponding 6-aryl (or alkyl)imino-4a,9-diaza-1,2,4a,9a-tetrahydro-6H-fluorenes. Coupling with thiourea under these conditions affords 6-cyanoimino-4a,9-diaza-1,2,4a,9a-tetrahydro-6H-fluorenes.
