Mechanistic approach of Os(Vlll) calalysed oxidation of 2-methylbutan -1-ol by chloramine-T

The oxidation kinetics of 2- Methyl butanol-1 have been studied by alkaline solution of Chloramine-T in presence of Os(VIII ) catalyst. The order of reaction with respect to Chloramine-T, 2-methyl butan-1-ol Osmium tetroxide has been studied respectively. Effect of temperature variation on the reaction rate has been observed. Zero effect of addition of paratoluene sulphonamide (PTS) on reaction rate was observed. A possible mechanism confirming to all the observed kinetic data have been collected and suitable mechanism has been suggested. The rate law derived on the basic of proposed mechanism is as -d[chloramine – T] / dt= K[chloramine – T] [OsO4] [2-methyl butan – 1- ol]
