A double mediatory system consisting of RuO4/RuO2 and Cl+/Cl- redox couples has been developed for the indirect electrooxidation of alcohols and aldehydes.The reaction proceeds in the following manner: (1) oxidation of the substrate with ruthenium tetraoxide (RuO4) in the organic layer, (2) regeneration of ruthenium tetraoxide from ruthenium dioxide (RuO2) with active chlorine species (Cl2 or +), and (3) oxidation of chloride ion to + on the anode in the aqueous layer.The range of applicability of the present procedure is discussed by oxidations of (1)secondary alcohols to ketones, (2) primary alcohols and aldehydes to carboxylic acid, (3) 1,n-diols to lactones and keto acids, and (4) carbohydrate derivatives.

Three 7-hydroxyalkanoic acids not previously reported in microorganisms were found in extracts from saponified whole cells of Mucor spp. grown under oxygen limiting conditions.On the basis of evidence from mass spectrometry, infrared spectroscopy, gas chromatographic procedures and chemical conversions, they were confirmed to be 7-hydroxydecanoic, 7-hydroxydodecanoic and 7-hydroxytetradecanoic acids.The racemates of the former two acids were synthesized and compared with the isolates.These acids were found in the hydrolyzates of extractable and residual parts of lyophilized cells with a chloroform-methanol (2:1) mixture.The hydroxy acid contents of eight species of the genus Mucor grown in stationary liquid medium were also determined.
