syn-diacetoxylation of alkenes and 1,2-oxyacetoxylation of terminal alkynes has been developed using (diacetoxyiodo)benzene as oxidant. A broad range of internal and terminal alkenes, including electron-rich as well as electron-deficient alkenes, gave the desired products in good to excellent yields with high diastereoselectivity (up to >99:1 dr). In addition the high catalytic activity of ironcatalysis for the

A palladium-catalyzed diacetoxylation of alkenes in the presence of peracetic acid and aceticanhydride was developed to produce diacetates efficiently and diastereoselectively. Due to its mild conditions, this method was suitable for a broad range of substrates encompassing conjugated and nonconjugated olefins.

The palladium-catalyzed diacetoxylation and trifluoromethanesulfonic acid-catalyzed diacetoxylation using inexpensive and environmentally friendly hydrogenperoxide and peracetic acid were successfully conducted with the help of microchemical technology. Excellent yield and selectivity were achieved in significantly shortened reaction times without the decomposition of explosive oxidants and further
The reactions of cerium (IV) ammonium nitrate and cobalt (III) acetate with 1,2-diphenylethanes in acetic acid. Evidence against the involvement of radical cations in the side-chain oxidation of alkylbenzenes by Co(OAc)3

The oxidation of 1,2- diphenylethane and 2,3-dimethyl-2,3-diphenylbutane by cerium(IV) ammoniumnitrate and Co(OAc)3 in aceticacid show that a radicalcation mechanism is plausible only in the reaction of the former oxidant.
