Initial stage of oxidation of lead acetate on Pt electrode in glacial acetate acid was studied using cyclic voltammetry and chronoamperometry. Results show that the initial oxidation kinetics corresponded to a model including progressive nucleation. With addition of benzene and under certain current density and temperature, the indirect organic electrosynthesis using lead tetraacetate as media could be carried out in one compartment and no lead metal was deposited on the counter electrode. Acetoxylation of acetophenone and oxidation of styrene were performed in this system and the yields are 68% and 35.6% respectively.

Key words: indirect electrochemical organic synthesis, sty-rene, undivided compartment, acetophenone, lead tetraacetate
