Structural Activity of Unsaturated Alcohols and Oxidation Towards Pyrazinium Chlorochromate

The kinetics of oxidation of allyl, crotonyl, styryl carbinol by pyrazinium chlorochromate (PzCC) has been investigated in 60% acetic acid medium. The order was found to be first order with respect to [oxidant], [substrate] and [H+.]. The rate of the oxidant decreased with increase in [PzCC] and inc...

Description
Summary:The kinetics of oxidation of allyl, crotonyl, styryl carbinol by pyrazinium chlorochromate (PzCC) has been investigated in 60% acetic acid medium. The order was found to be first order with respect to [oxidant], [substrate] and [H+.]. The rate of the oxidant decreased with increase in [PzCC] and increased with increase in the percentage of Acetic acid. The addition of sodium perchlorate did not show any change in rate constant.Based on the kinetic results, the mechanism between unsaturated alcohol and chromium (VI) oxidant is proposed. The reactivity of unsaturated alcohols was observed to be Allyl alcohol
