Abstract:A series of cyanonitrovinyl neonicotinoids were designed and synthesized via five steps in about 35% overall yields. All compounds were structurally characterized by (1)H nuclear magnetic resonance (NMR), (13)C NMR, infrared (IR), and high-resolution mass spectrometry (HRMS), and single-crystal X-ray diffraction analysis of 2-[1-[(6-chloropyridin-3-yl)methyl]-2-imidazolidinylidene]-2-nitroacetonitrile revealed that the double bond is (E)-configured. The preliminary agriculture bioassay indicated that one compound exhibited moderate insecticidal activity against pea aphid.
