Oxidation of crotyl alcohol by N-chloro-4-methylbenzene sulphonamide in acidic medium and in alkaline media in the presence of os(VIII) catalyst-a kinetic pathway

The kinetic pathway of oxidation of crotyl alcohol by sodium salt of N -chloro-4-methylbenzene sulphonamide (chloramine-T) in acidic and alkaline medium has been studied. The speciation of chloramine-T has been made to suggest a proper and reasonable reaction mechanism. The thermodynamic quantities such as activation energy and activation entropy are evaluated in acidic as well as in catalysed alkaline medium. An anticipated reaction mechanism has been suggested.

Cyclic α-acetoxynitrosamines: Mechanisms of decomposition and stability of α-hydroxynitrosamine and nitrosiminium ion reactive intermediates

A study of the kinetics and mechanism of the decay of α-acetoxy-N- nitrosopyrrolidine and α-acetoxy-N-nitrosopiperidine are reported. The compounds differ in reactivity by more than 2 orders of magnitude at physiological pH. On the basis of thermodynamic

AUTOOXIDATION OF ACETYLENES AND THEIR DERIVATIVES. XXV. 1-PHENYL-4-PENTEN-1-YN-3-0L AND 1-PHENYL-4-HEXEN-1-YN-3-OL

During the autooxidation of secondary enynyl alcohols attack by oxygen takes place at the C-H bonds at the α position to the triple and double bonds and the hydroxyl group.The initially formed unstable hydroxyhydroperoxides dissociate under the oxidation conditions into the corresponding enynyl ketones, acetylenic keto epoxydes, and products from degradation of the carbon skeleton.
