OXIDATIVE COUPLING OF 4a,9-DIAZA-1,2,4a,9a-TETRAHYDROFLUORENES. 1. SYNTHESIS OF MONONUCLEAR HETEROCYCLIC QUINONEDIIMINES

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 condit

SYNTHESIS OF POLYNUCLEAR HETEROCYCLIC QUINONE IMINES - DERIVATIVES OF 4a,9-DIAZAHYDROFLUOREN-6-ONES

When derivatives of 4a-9-diaza-1,2,4a,9a-tetrahydrofluorene are oxidized by treatment with MnO2, the corresponding derivatives of 4a,9-diaza-1,2,4a,9a-tetrahydrofluoren-6-one are obtained.In a number of cases the reaction is accompanied by dehydrogenation
