Kinetic study of iridium(III) catalyzed oxidation of D-mannitol and erythritol by N-bromosuccinimide in acidic medium

Kinetic investigations on iridium trichloride catalyzed oxidation of D-mannitol and erythritol by acidic solution of N-bromosuccinimide (NBS) in the presence of mercuric acetate as a scavenger for Br- have been carried out in the temperature range 30-45 °C. The reactions follow identical kinetics. The rate shows a first-order dependence on [NBS] in lower concentration range which tends to zero-order at its higher concentrations. A first-order dependence on [IrIII] is also observed. Negligible effect of [substrate], [Hg(OAc)2] and ionic strength have been observed. Addition of [H+], [Cl-] and succinimide shows a negative effect. Activation parameters have been computed and a suitable mechanism conforming to above results has been proposed.

A novel mechanism for the oxidation of erythro-series pentoses and hexoses by N-arylbromosulphonamides in alkaline medium

Kinetic studies of the oxidation of D-mannose, D-glucose, D-fructose, L-arabinose and D-ribose by bromamine-T (sodium N-bromo-p-toluenesulphonamide or BAT) and bromamine-B (sodium N-bromobenzenesulphonamide or BAB) in alkaline medium were investigated at 30°C. The rate of the reaction was first order both with respect to the oxidant and the sugar and second order with respect to [HO-]. The addition of the reaction product, p-toluenesulphonamide (PTS) or benzenesulphonamide (BSA), and the variation of ionic strength of the medium have no effect on the rate. The rate decreases with decrease in dielectric constant of the medium and values of dAB, the size of activated complex, were calculated. Proton inventory studies were made in H2O-D2O mixtures. The activation parameters of the reaction were computed from Arrhenius plots. HPLC and GLC-MS analysis of the products indicated that the sugars were oxidized to a mixture of aldonic acids consisting of arabinonic, ribonic, erythronic and glyceric acids. A general mechanism consistent with the observed results has been proposed.

KINETICS AND MECHANISM OF Ru(III) CATALYSED OXYDATION OF SOME POLYHYDRIC ALCOHOLS BY N-BROMOSUCCINIMIDE IN ACIDIC MEDIA

Kinetics of oxydation of ethylene glycol, glycerol, erythritol and dulcitol by acidic solution of N-bromosuccinimide (NBS) in presence of ruthenium(III) chloride as a homogeneous catalyst and mercuric acetate as scavenger in the temperature range of 30-50 deg C have been reported.The reactions follow identical kinetics, being first order in each NBS, substrate and Ru(III).Zero effect of , and ionic strength has been observed.A negative effect of succinimide and acetic acid is observed while shows the positive effect on reaction velocity.Various activation parameters have been computed.The products of the reaction were identified as the corresponding acids.A suitable mechanism consistent with the experimental results has been proposed.
