Derivatives of phenyl tribromomethyl sulfone as novel compounds with potential pesticidal activity
A halogenmethylsulfonyl moiety is incorporated in numerous active herbicides and fungicides. The synthesis of tribromomethyl phenyl sulfone derivatives as novel potential pesticides is reported. The title sulfone was obtained by following three different synthetic routes, starting from 4-chlorothiophenol or 4-halogenphenyl methyl sulfone. Products of its subsequent nitration were subjected to t...
متن کاملSynthesis, Characterization, Antimicrobial and Pesticidal Activity of Organoarsenic(iii) and Organoantimony(iii) Complexes with N
Some new Sb(III) and As(III) complexes of N∩S donor ligands N’[1-(2-oxo-2H-chrome-3yl-ethylidene] hydrazinecarbodithionic acid methyl ester (L1H) and N’ [1-(2-oxo-2H-chrome-3yl ethylidene] -hydrazinecarbodithionic acid benzyl ester (L2H) have been synthesized. All the synthesized compounds were characterized by elemental analyses, melting point determinations and a combination of electronic, IR...
متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
15 صفحه اولBacillus thuringiensis and its pesticidal crystal proteins.
During the past decade the pesticidal bacterium Bacillus thuringiensis has been the subject of intensive research. These efforts have yielded considerable data about the complex relationships between the structure, mechanism of action, and genetics of the organism's pesticidal crystal proteins, and a coherent picture of these relationships is beginning to emerge. Other studies have focused on t...
