N'-SUBSTITUTED INSECTICIDAL N,N'-DIACYL HYDRAZINES, INSECTICIDE AND METHOD OF OBTAINING 3-ALKOXY-2-(SUBSTITUTED) BENZOIC ACID OR ESTER AS WELL AS METHOD OF OBTAINING 2-(SUBSTITUTED BENZOIC ACID CONTAINING CONDENSED HETEROCYCLIC RING AT ITS 3,4 POSITIONS

摘要

Insecticidal compounds having the formula N-(2-Ra-3-Rb-benzoyl)-N'-(2-Rc-3-Rd-4-Re-5-Rf-benzoyl)-N'-Rg-hydrazine, where Ra is a halogen or a lower alkyl; Rb is lower alkoxy; Rc-f are selected from hydrogen, bromo, chloro, fluoro, lower alkyl and lower alkoxy; and Rg is a (C4-C6)alkyl or (C4-C6)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.
