A series of cyanonitrovinyl neonicotinoids were designed and synthesized via five steps in about 35% overall yields. All compounds were structurally characterized by 1H nuclear magnetic resonance (NMR), 13C 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. Springer-Verlag 2010.
One step from nitro to oxime: a convenient preparation of unsaturated oximes by the reduction of the corresponding vinylnitro compounds

A series of novel unsaturated oximes were conveniently prepared from the corresponding vinylnitro compounds by reduction with SnCl2·2H2O. The structures of the oximes were characterized by 1H and 13C NMR, IR and HRMS, and X-ray crystallography analysis of 1-(6-chloro-pyridin-3-ylmethyl)-4,5-dihydro-1H-imidazole-2-carbaldehyde oxime 2a reveals that, the hydroxyl group is arranged in a trans configuration. Some evidences from a brief investigation suggest that these oximes seem to be formed by reduction of the aci form of nitro aliphatic compounds.
