The stable pyridinium salt of o-iodoxybenzoic acid (PIBX) that is easy to obtain can serve as a convenient substitute of IBX as an oxidant. PIBX is safer, has neutral properties behaves as an equivalent to IBX in the oxidation of alcohols to ketones or aldehydes in polar solvents (DMF, DMSO), and provides higher oxidation rate in THF due to better solubility.

Various Various factors related to the yield and selectivity for the indirect electrooxidation of diidopropylidene-glucose (1) to the ulose 2 with ruthenium tetraoxide (RuO4) and chloride ion are investigated.The following is found to be optimum conditions: pH, ca. 10:solvent system, carbon tetrachloride and t-butyl alcohol (ca.9:1); current density, 10-40 mAcm2-; temperature, 20-40 deg C; catalyst amount, 2 molpercent of RuO2.2H2O (based on 1).The optimized electrolysis affords the desired 2 in 90 percent yield along with a trace of the cleavaged product 3 (0.2percent) by an overoxidation.

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.
