Preferred Abstract (Original):

Kinetics of osmium tetroxide catalyzed-oxidation of the studied fluoroquinolones by potassium hexacyanoferrate(III) in alkaline medium were studied. The rate was found to be independent on the concentration of hexacyanoferrate(III), and first order with respect to both fluoroquinolone and OsO4. An empirical rate law was derived for the reaction, and the effect of various variables on the rate of reaction was studied. Thermodynamic parameters (Ea, ΔH*, ΔS*, ΔG*) were also calculated.
