to be superior to mitomycinC in potency, efficacy, and therapeutic ratio in the P-388 assay. The most active substituents at the mitosane 7 position included aziridine, 2-methylaziridine, propargylamine, furfurylamine, methyl glycinate, and 3-aminopyridine. Mitomycin A and the 7-aziridino, 7-(2-methylaziridino), and 3-aminopyridine analogues were less leukopenic than mitomycinC. Certain other analogues
3-Halo-2,6-dinitro-4-trifluoromethylanilines having hydrocarbon substituents on the nitrogen atom. The hydrocarbon substituents can be alkyl, alkenyl, alkynyl or a portion of a heterocyclic group. The compounds are especially useful as intermediates for preparing herbicidal dinitro-1,3-phenylenediamines.
N,N'Substituted-1,3-phenylenediamine compounds having a trifluoromethyl and a nitro group on the aromatic ring. The compounds are useful as herbicides.

N-Phenyl or N-benzoyl 2-halogenoallylamines (5) or (10) react successively with phenyl-lithium and lithium naphthalenide at –78 °C to give the intermediates (4) or (11), which on reaction with electrophiles (water, deuterium oxide, dimethyl disulphide, aldehydes, ketones, or allyl bromide) yield functionalized allyl amines (6) and (12). The corresponding N-alkyl derivatives (9) afford prop-2-ynylamines
