The tripeptide alanylalanylalanine reacts with either HOCl or HOBr to form a N, Ndihalopeptide. These compounds decompose to the N-halo-N'-(a-iminoket0)peptides plus halide ion. The rate constants for these reactions in 0.4-M NaCl were determined to be (PH 6.7) k4 = 1.06 x 1015e 18,400'RT min-' (PH

At 298 K the rate constant for the decomposition of N-chloroleucine has the constant value 3.20 >: lo-\* s-' over the range pH 5-12, increases with increasing acidity at pH < 5, and increases with pH a t pH > 12. A mechanism is put forward which explains these results.
The homogeneous gas-phase decomposition kinetics of silane has been investigated using the single-pulse shock tube comparative rate technique (T = 1035-1184ยฐK, P ~d = 4000 Torr). The initial reaction of the decomposition SiH4 ! + SiHz + H2 is a unimolecular process in its pressure fall-off regime w
The kinetics and mechanism of the thermal decomposition of n-propylsilane have been studied by the single pulse shock tube-comparative rate technique a t pressures around 4700 torr between 1095-1240 K.
