To degrade the highly toxic pesticide into less harmful components, we have synthesized four nickel complexes of naphthalimide based organic ligands. These complexes catalyze the hydrolysis of phosphorothioate bonds of organophosphates in an aqueous medium. The metal complexes {[Ni(L1)2]–[Ni(L4)2]} were synthesized by the electrochemical method and characterized using single-crystal X-ray crystallography and mass spectrometry. Analytical techniques revealed that complexes are mononuclear and possess octahedral geometry. The rate of degradation of chlorpyriphos and parathion methyl was evaluated using 31P NMR and LC-MS chromatogram. The by-product of chlorpyriphos upon catalytic degradation with complex was confirmed from mass spectrometry. It was found that chlorpyriphos degrade into 3,5,6-trichloropyridin-2-ol after 50 minutes of incubation with catalyst. However, parathion methyl took only 20 minutes to hydrolyze into its by-product. Moreover, the inhibition assay of acetylcholinesterase was performed for pesticides in the presence of metal complex and the interesting outcome was recorded.
New diisocyanates containing sulfur and a process for their preparation

, (2008/06/13)
The invention is directed to new sulfur-containing diisocyanates in which a mercapto, sulfoxo or sulfone group joins two aromatic nuclei together or joins an aromatic nucleus to an aliphatic group and in which at least one of the aromatically bound isocyanate groups is in the ortho-position to the sulfur atom. The invention is also directed to a process for the preparation of these new sulfur-containing diisocyanates and to their use in the isocyanate polyaddition process for the production of polyurethanes.
