Application of sulfonamide compounds in reinforcement of plant stress resistance and pesticide containing sulfonamide-class compound

The invention relates to the field of pesticides, and discloses an application of sulfonamide compounds in reinforcement of plant stress resistance and a pesticide containing the sulfamide compounds. The sulfamide compounds have structures shown in a formula (1); and the active ingredient of the pesticide for reinforcing the plant stress resistance provided in the invention is at least one sulfonamide compound shown in the formula (1), and the active ingredient content is 0.1-100wt% calculated by the total weight of the pesticide. The sulfonamide compounds provided in the invention can remarkably reinforce plant tolerance to common abiotic stresses (coldness, drought, high temperature, osmotic pressure and the like) in environments.

Effect of para substitution on dissociation of N-phenylbenzenesulfonamides

The reaction of substituted anilines and benzenesulfonyl chlorides has been used to prepare 49 substituted N-phenylbenzenesulfonamides of general formula 4-X-C6H4SO2NHC6H4-Y- 4′. Their purity was checked by elemental analysis. The substituents X and Y include H, CH3, CH3O, Cl, Br, CN, and NO2. The dissociation constants of all compounds were determined by potentiometric titration in methanol, acetonitrile, N,N-dimethylformamide, and pyridine. The obtained dissociation constants, pKHA, were correlated with various sets of substituent constants. It was found that the effects of substituents X and Y on the dissociation are best described by using the Hammett equation with σp constants and the Yukawa-Tsuno equation with σp- and σp constants, respectively. This result confirms the direct conjugation of Y substituent with the reaction centre. The explained variability using the additive model was above 96% in all the solvents used. The data also provided information about the transmission effect of the SO2 group. The average dissociation constants were further processed by the latent variables methods, principal components and conjugated deviations analyses.
