Abstract

The reaction of the title substrate with a series of secondary alicylic amines has been the subject of a kinetic study in aqueous solution, 25 OC, ionic strength 0.2 M (KCl). With the amine in excess, pseudo-first-order rate constants (kobsd) are observed. The order in amine varies from 1 to 2 depending on the basicity of the amine and the reaction conditions. A reaction scheme is deduced on the basis of the existence of zwitterionic (Ti) and anionic ( ...
