The oxidative behavior of isosafrole (ISF) in non-aqueous system on Pt was investigated by cyclic voltammery. When scanning from -0.55 to 1.95 V (vs Ag/AgCl electrode) at a certain scan rate, two oxidation peaks and one reduction peak appeared. By scanning at different scan rate, the electro-oxidative behavior of isosafrole on Pt was confirmed to be controlled by concentration diffusion, as well as chemical reaction rate. By comparing the two isomers, ISF and SF safrole, the reactive mechanism was dcecussed. Moreover, the active oxidation group of ISF was identified to be the C=C from allyl by developing the in-situ surface enhanced Raman specrum.
