Behavior of IrCl3 as a Homogeneous Catalyst on the Oxidation of N-Acetylglucosamine in Acid Medium and Uncatalyzed Reaction in Alkaline Medium with Bromamine-B: Exploration of Kinetic, Mechanistic and Catalytic Chemistry

Abstract

The experimental rate laws for the oxidation of N-acetylglucosamine with bromamine-B are: − d[BAB]/dt = k / [BAB] 1 [GlcNAc] 0.69 [HClO 4 ] −0.76 [IrCl 3 ] 0.48 [BSA] −0.33 in acid medium and -d[BAB]/dt = k / [BAB] 1 [GlcNAc] 1 [NaOH] 0.79 in alkaline medium. The IrCl 3 catalyzed reaction is thirteen fold faster than uncatalyzed reaction. Appropriate mechanisms and rate laws were deduced. -CH 3 COOH -NH 3 -CO 2 Keywords IrCl 3 catalysis • N-Acetylglucosamine • Bromamine-B • Acid and alkaline media • Kinetics-mechanism

Exploration of Ruthenium (III) Chloride catalysis on oxidative conversion of aryloximes to arylaldehydes with bromamine-B: A kinetic and mechanistic approach

“…These compounds can be easily prepared by the bromination of CAT and CAB and were found to be advanced oxidizing agents than the chloro compounds. Literature says that relatively less attention [11][12][13] was paid towards the kinetics and mechanism of oxidation of organic substrates involving BAT and BAB as oxidizing agents. Our preliminary kinetic runs assessment began with CAT and CAB as oxidants for the oxidative conversion of aryloximes in acid medium under diverse experimental conditions.…”
