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.

experimental part, p. 418 - 424 (2010/08/05)
A series of unsymmetrical difluoroboron (BF2) complexes with pyridine and imidazoline were synthesized by reaction of new chelating ligands (arylmethyl-imidazolidinylidene)-pyridin-2-yl-amine with boron trifluoride diethyl etherate. All the ligands and BF2 complexes were structurally characterized by IR, HRMS, 1H, 13C, 11B, and 19F NMR,indicating the bidentate complexation of imidazoline nitrogen and the pyridine nitrogen to the boron center. Evaluation of agricultural bioactivities showed that some of the BF2 complexes exhibited moderate fungicidal activities, and most of the BF2 complexes exhibited higher activities than the none-BF2 complexed substrates.
