A kinetic study of the decomposition reactions of N ‐bromoalanine, N ‐bromo‐2‐aminobutyric acid, and N ‐bromonorvaline shows them to be first‐order with respect to N ‐bromoaminoacid concentration and independent of both excess aminoacid and pH over the interval pH 9–11. In this pH range the mean rate constants at 298 K were 1.20 × 10 −3 s −1 , 1.37 × 10 −3 s −1 and 1.28 × 10 −3 s −1 , respectively. © 1993 John Wiley & Sons, Inc.
