Hydrolysis Of

A study is made on the kinetic salt effect on the reaction of hydrolysis of several charged esters in alkaline media. The results are interpreted on the basis of the coulombic interaction, the salting in of hydroxide ion and a third component depending on size of the substrate.

The acid hydrolysis of 1 assisted by the neighbouring amide group was kinetically investigated and salt effects were studied; the thermodynamic activation parameters calculated for the acid hydrolysis of other substrates (3–6) indicate that the methyl group in the side chain works on the enthalpic or on the entropic factor depending on the size of ring formed.
