Iodine-assisted chemical and electrochemical asymmetric dihydroxylation of various olefins in I2-K2CO3-K2OsO2(OH)4 and I2-K3PO4/K2HPO4-K2OsO2(OH)4 systems with Sharpless' ligand provided the optically active glycols in excellent isolated yields and high enantiomeric excessses.Iodine (I2) was used stoichiometrically for the chemical dihydroxylation, and good results were obtained with nonconjugated olefins in contrast to the case of potassium ferricyanide as a co-oxidant.The potentialily of I2 as a co-oxidant under stoichiometric conditions has been proven to be effective as an oxidizing mediator in electrolysis systems.Iodine-assited asymmetric electro-dihydroxylation of olefins in either a t-BuOH/H2O(1/1)-K2CO3/(DHQD)2PHAL-(Pt) or t-BuOH/H2O(1/1)-K3PO4/K2HPO4/(DHQD)2PHAL-(Pt) system in the presence of potassium osmate in an undivided cell was investigated in detail.Irrespective of the substitution pattern, all the olefins afforded the diols in high yields and excellent enantiomeric excesses.A plausible mechanism is discussed on the basis of cyclic voltammograms as well as experimental observations.

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.

In the presence of a catalytic amount of bis(3-methyl-2,4-pentanedionato)nickel(II) (Ni(mac)2), various glycidyl esters are converted into the corresponding glycerol monoester derivatives with molecular oxygen in good to high yields.
