REACTION CAPACITI g-(R-PHENYLSULFONYLOXAMI-DO)-BUTANOIC ACIDS
The ionization constants of g-(R-phenylsulfonyloxamido)-bu-tanoic acids were measured. It was showed that their pKa good correlat with Hammet s-constants. The quantitative assesement of substituents’ in benzene nucleus of molecules was carried out by Hammet correlation analysis method.
