Seventeen N'-tert-butyl-N'-aroyl-N-(alkoxycarbonylmethyl)-N-aroylhydrazines were synthesized, and their insecticidal activities against armyworm (Leucania separata (Walker)) were tested. The conformation and structure of compound 1b was studied by H-1 NMR spectroscopy and X-ray crystallography. The crystal structure belongs to the orthorhombic system and the N-N bond adopts a gauche conformation, which was assumed to be the active conformation, with a dihedral angle of 69.9 degrees.
