Abstract
Peroxyoxalate chemiluminescence, the most efficient nonenzymatic chemiluminescence reaction known, is used to demonstrate mechanistic features of analogous ester hydrolysis reactions. The effect of the leaving group pKa and a comparison between nucleophilic and general-base catalysis are demonstrated visually by the kinetics of the light-generating reaction. The demonstration is targeted for undergraduate organic chemistry students but is easily modified for a range of audiences.
