Abstract
|
|
|
|
Kinetic studies on the nucleophilic reactions of p-substituted benzylnitrates with substituted anilines have been conductometically carried out in 50-100% CH3CN-CH3OH mixtures. From the kinetic data, Hammett ρC and ρN values, Brφnsted β values, and solvatochromic coefficients were determined in order to examine the transition state variations caused by changes in substituents and solvent properties. It is concluded that the reaction proceeds via a synchronous SN2 mechanism in which bond formation is more advanced than bond cleavage.
