Abstract

Abstract: The kinetics of ester cleavage of 4-carboxy-2-nitrophenyl alkanoates (1)(C2-CS) and of 2-carboxy-4-nitrophenyl alkanoates (2)(C2, C4, C6, C8) in an aqueous phosphate buffer (pH 11.7) containing a-or j3-cyclodextrin (a-or j3-CD) show various types of behavior. Depending on the ester, its acyl chain, and the CD, the kinetics show acceleration (with or without saturation), retardation, acceleration and retardation, retardation and acceleration, ...
