However, in a nonaqueous solvent, the hydrolysis is prevented and the epoxide ring can be isolated as the product. Then, the oxygen is inserted on top. References 19,21, Vollhardt, Peter, and Neil E. Draw the intermediate of this reaction. Jorge A. For more explanation of how this reaction leads to vicinal diols, see below. This reaction was performed under photochemical irradiation [23,24]but weak selectivity and low isolated yields were observed.

    This procedure has considerable advantages over the previously reported oxidation methods, because no other positions of the molecule are oxidized concomitantly, it avoids the use of halogenated solvents, and allows easy recovery of the reaction products.

    A cyclic osmic ester is formed. A syn-1,2-ethanediol is formed. Proton transfer from the acid catalyst generates the conjugate acid of the epoxide, which is attacked by nucleophiles such as water in the same way that the cyclic bromonium ion described above undergoes reaction.
