    • 8. An oil bath with an effecient stirrer was partitioned by wire mesh to ensure a uniform temperature throughout the experiment. The temperature in each section of the oil bath was confirmed to be same. Normal phase HPLC was performed using ethyl acetate : hexane (30 :70) as the eluent. Absorbance was recorded at fixed wave length of 290 nm.

    • 10. All solvents were HPLC grade and used directly without further purification. In the case of benzene and THF, rates were obtained from both distilled and non-distilled HPLC grade solvents. The half-life difference between distilled and non-distilled solvent was negligible.
