Title compds. (I; R1=halo, CF; R2=H, C1-4 alkyl; R3=H,F, C1-3 fluoroalkyl; n=1-3; R= Na, K, Ca, Ag, Li, NH2, triethylammonium), useful as herbicides, insecticides and ectoparasiticides, were prepd. Thus, 35g 3-nitro-5-(trifluoromethyl)-N'-(2,2,3,3,-tetrafluo- ropropionyl)-0-phenylenediamine kept in N NaOH for 24 hr at room temp. gave I(R1= CF3; R2=H; R3=H; n=1; R=Na).
