Abstract:

Ten new N-oxalyl derivatives of neonicotinoid compound were designed and synthesized. Their structures were confirmed by 1H NMR spectra, elemental analysis and X-ray diffraction. The preliminary insecticidal activities of the new compounds were evaluated. The results of bioassays indicate that the title compounds exhibit moderate insecticidal activities. Surprisingly, the insecticidal activity of compound 7b against bean aphids at 200 mg/kg is 100%, which is comparable to that of the commercialized imidacloprid.

Key words: Neonicotinoid; N-Oxalyl derivative; Insecticidal activity; Bean aphid; Imidacloprid
