The title reaction has been suggested to proceed through a zwitterionic tetrahedral intermediate with a change in the rate determining step on the basis of the curved Bronsted-type plots obtained. The curvature center of the curved Bronsted-type plots is at pK(a) = 6.4 regardless of the electronic nature of the substituent X in the benzoyl moiety.
