Abstract
Insecticidal compounds having the formula N-(2-R.sup.a -3-R.sup.b -benzoyl)-N'-(2-R.sup.c -3-R.sup.d -4-R.sup.e -5-R.sup.f -benzoyl)-N'-R.sup.g -hydrazine, where R.sup.a is a halogen or a lower alkyl; R.sup.b is lower alkoxy; R.sup.c-f are selected from hydrogen, bromo, chloro, fluoro, lower alkyl and lower alkoxy; and Rg is a (C.sub.4 -C.sub.6)alkyl or (C.sub.4 -C.sub.6)alkenyl; as well as compositions comprising an agronomically acceptable carrier and an insecticidally effective amount of such compounds; and methods of using such compounds and compositions. Also, methods for the production of the compounds and their intermediates, which methods comprise admixing a 3-amino-2-(substituted)-benzoic acid, sodium nitrite and methanol under acidic conditions.
