1,3-Dithiolane-containing nitromethylene derivatives, as candidates for screening as neonicotinoid insecticides, were synthesized by reaction of compound (4) with 1,2-ethanedithiol. Compounds 7a-g were obtained via Mannich reaction of (E)-1-((1,3-dithiolan-2-yl)methyl)-2-(nitromethylene)imidazolidine (6), primary amines and formaldehyde. The synthesized compounds were identified by 1H NMR, IR spectroscopy and elemental analysis. Preliminary bioassays indicated that most of the compounds had moderate insecticidal activity against Aphis craccivora. The relationship between molecular structure and biological activity is discussed.

Paragraph 0026; 0027, (2016/03/12)
This invention relates to the synthesis of chemical compounds and particularly to methods for the preparation of (4,6-dihalo-pyrimidin-5-yl)-acetaldehydes. The methods involve preparing a compound of the following general formula V from a compound of the following general formula IV through hydrolysis under the action of mercury dichloride and calcium carbonate, according to the following equation: wherein X is Cl or Br. The methods offer the benefits of use of highly available materials, high step yields, moderate reaction conditions, simply post-processing and purification, and suitability to industrialized production.
