Isoenthalpy Catalytic Effects of Pyridines in Reactions of Phenyloxyrane with N-Aroylbenzenesulfonamides

Аннотация

Additive nature of the combined effect of the structure (X, Y substituents) and temperature on the rate and free activation energy has been established for the reactions of phenyloxirane with Y-substituted N-aroylbenzenesulfonamides catalyzed by X-substituted pyridines. The cross reaction series is isoenthalpic with respect to the structural effects. The mechanism of the catalytic process has been discussed.
