Electrooxidative Fission of Carbon–Carbon Double Bond in a K2OsO2(OH)4/HIO4 Double Mediatory System

Abstract Electrooxidation of olefins in the presence of potassium osmate (0.04 molar amount) and periodic acid (0.5 molar amount) afforded the corresponding carbon–carbon double bond cleavage products in moderate to good yields, where the turnover number of periodic acid reached ca. 3.
