Seethalakshmi Ramaswamy College (Autonomous), Trichy-820 002 Manuscript received 24 December 1991, revised 8 July 1992, accepted 4 August 1992 Kinetics of oxidation of 2,6 diphenyl-4-piperldone, 3-alkyl and 3,5-dimethyl substituted 4 piperidones with TI II In aqueous acetic acid (80%,v v) in the presence of sulphuric acid (0 75 mol dm-2) at constant ionic strength (μ =2 25 M) over the temperature range 30- 55° have been investigated The reactions obey second order kinetics. Dependence on acidity is unity Added sodium sulphate does not have any effect. Activation parameters have been calculated and the structure-reactivity relationships discussed. A mechanism involving fast enolisation step is postulated.
