✦ Synopsis

This article reports the kinetics of the decomposition of N-bromoserine formed rapidly by bromation of serine by BrO -. The main decomposition products are glycolaldehyde, ammonia, carbon dioxide, and bromide ions at pH < 11.5, and P-hydroxypyruvic acid, ammonia, and bromide ions at pH > 11.5. The reaction is of order one with respect to N-bromoserine, and is independent of ionic strength and excess serine. The rate constant increases with increasing pH at pH > 11 and with decreasing pH at pH < 8, and over the range pH 8-11 has the constant value 1.67 x s-' at 298 K.

The decomposition of various N-chloroalkylamines and N-chloroalcoholamines was investigated kinetically at pH 4-12 and in strongly alkaline media. The rate of Nchloramine decomposition increased with increasing pH above pH 10, remained virtually constant over the pH range 7-10 and again increased wi

Under anaerobic conditions S-nitrosothiols 1 a Β± e undergo thermal decomposition by homolytic cleavage of the SΓ€N bond; the reaction leads to nitric oxide and sulfanyl radicals formed in a reversible manner. The rate constants, k 1 , have been determined at different temperatures from kinetic measur
