The new derivatives are 1-amino-fluoren-9-ones substituted in position 1 by a dialkylamino radical or a nitrogenous heterocyclic ring and possibly also substituted in at least one other position by a halogen atom, a trihalogenomethyl radical, a trifluoromethylsulfonyl radical and/or a nitro radical.
