Oxidation of Cobalt(III) Complexes of Α-Hydroxy Acids by Nicotinium Di Chromate (NDC) in the Presence of Dimethyl Diocta Decyl Ammonium Chloride (DDAC) - A Kinetic and Mechanistic Study

Author(s): K. Murali, Mansur Ahmed and Mohammed Nawaz

The kinetics of induced electron transfer reaction has been attempted presently with nicotinium dichromate (NDC) and pentaammine cobalt (III) complexes of α-hydroxy acid in the presence of micelles. The nicotinium dichromate (NDC) oxidizes cobalt (III) bound and unbound α-hydroxy acids. In nicotinium dichromate (NDC) induced electron transfer in the complex, the intermediate radical formed dissociates in a nearly synchronous C-C bond cleavage and the rest of it proceeding with C-H fission yielding cobalt (III) complex. With increase in surfactant (dimethyl dioctadecyl ammonium chloride) (DDAC) concentration, an increase in the rate was observed.
