Abstract
The kinetics of the addition of arenesulfinic acids to 4-substituted 2 -nitroethenylarenes was studied by means of UV spectrophotometry. The effect of 4-substituting groups in benzenesulfinic acids, and the chan ge in reactivity of nitroethylene system due to typical electron-donat ing and electron-withdrawing groups were investigated. The substituent effect on benzenesulfinic acid fits Hammett's equation, p-value at 29 8 K being -1.12 (r = 0.987). Kinetic studies were carried out at 288-3 08 K, and the activating energy and the enthalpy of activation were de termined.
