✦ Synopsis

Oxidative coupling of 4a,9-diaza-l,2,4a,9a-tetrahydro-gH-fluorene with primary amines and ammonia in the presence of MnO 2 gives the corresponding 6-aryl (or alkyl)imino-4a,9-diaza-l,2,4a,9a-tetrahydro-6H-fluorenes.

Coupling with thiourea under these conditions affords 6-cyanoimino-4a,9-diaza-l,2,4a,9a-tetrahydro-6Hfluorenes.
