The critical micelle concentration (CMC) of N-hexadecyl-4-cyanopyridinium (HCP) bromide, determined by conductivity or fluorescence quenching, was 7–8 ∗ 10-4 M. The observed rate constants for the hydrolysis of HCP below the CMC increased with the concentration of this amphiphile from 2 ∗ 10-6 M up to the CMC. The product ratio (pyridone/amide) also varied with HCP concentration. The analysis of both
