    摘要: Insecticidal compounds having the formula N-(2-R.sup.a -3-R.sup.b -4-R.sup.h -benzoyl)-N'-(2-R.sup.c -3-R.sup.d -4-R.sup.e -5-R.sup.f -benzoyl)-N'-R.sup.g -hydrazine wherein R.sup.a is a halo or lower alkyl; R.sup. b is lower alkoxy, optionally substituted with halo (preferably fluoro); R.sup.c is selected from hydrogen, halo, lower alkyl, lower alkoxy, lower alkoxy lower alkyl, and nitro; R.sup.d, R.sup.e and R.sup.f are each independently selected from hydrogen, bromo, chloro, fluoro, lower alkyl, lower alkoxy, and lower alkoxy lower alkyl; R.sub.g is a (C.sub.4 -C.sub.6)alkyl; R.sup.h is hydrogen, lower alkoxy, lower alkyl, or when taken together with R.sup.b is methylenedioxy (--OCH.sub.2 O--), 1,2-ethylenedioxy (--OCH.sub.2 CH.sub.2 O--), 1,2-ethyleneoxy (--CH.sub.2 CH.sub.2 O--) or 1,3-propyleneoxy (--CH.sub.2 CH.sub.2 CH.sub.2 O--) wherein an oxo atom is located at the R.sup.b position; and the substituents R.sup.c and R.sup.d, or R.sup.d and R.sup.e, or R.sup.e and R.sup.f when taken together can be methylenedioxy or 1,2-ethylenedioxy 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 either admixing a 3-amino-2-(substituted)-benzoic acid, sodium nitrite and methanol under acidic conditions or admixing a 3,4-fused heterocyclic benzoic acid and an alkyl lithium reagent followed by subsequent reaction with an electrophilic reagent.
