    • 2O (9 g) was dissolved in aqueous HCl (50 mL, 18%), and a small amount granular Zn was added. Sodium thiocyanate (5 g) was added, and after the transient color faded, additional sodium thiocyanate (12 g) was added. The solution was decanted from the unused Zn, and stored in a clean reagent bottle. Upon mixing the colorless reagent with the tested solution, the appearance of deep red color indicates peroxide presence. Since the presence of ferrous salts, used to decompose the peroxides, can lead to a false negative result with the sodium ferrothiocyanate reagent, standard potassium iodide/starch test paper was used to follow the peroxide presence after the quench.

    • 3CN. A platinum rod was utilized as the auxiliary electrode. Cell resistance was corrected utilizing positive feedback IR compensation incorporated in the M270 software. Typical measurements were conducted in the following manner. The sodium methoxide solution was placed in the voltammetry cell and degassed with argon for 30 min. At this point background voltammograms were taken at all sweep rates to be investigated. An amount of the electroactive substrate needed to bring the concentration to 0.01 M was then added to the voltammetry cell and the solution stirred until the substrate was completely dissolved. At this point voltammatry measurements were begun. After each voltammetric run the solution was stirred and the working electrode polished to remove material adsorbed to the working electrode surface. (b) Preparative potentiostatic electrooxidations were performed on a Princeton Applied Research EG&G Model 263A potentiostat, equipped with a modified power amplifier with a current output capability of 2 A.

    • All nonhydrolytic reactions were performed in solvents either dried according to standard procedures or purchased from Aldrich. Analytical TLC was performed on silica gel 60F-254 plates (Whatman). Flash chromatograpby was performed with Fisher silica gel (grade 60, 200-425 mesh).
