In contrast to current opinion, osmium tetraoxide reacts even with very electron-poor olefins.For example, both partially and fully fluorinated osmate(VI) esters 2 are thus formed from fluoroolefins 1 by cycloaddition.Hydrolysis of the osmate(VI) esters leads to the corresponding 1,2-diols 3 and, eventually, consecutive fluoroorganic products by HF elimination.A catalytic version of this route opens a new, general, and efficient entry to oxidation products in fluoroolefin chemistry.Tetrahalide ethylene derivatives of formula split off oxalyl halide upon thermal treatment with the complexes py2O2OsX2 thus being formed in good yields. Key Words: Osmium tetraoxide, oxidation with / cis-Hydroxylation, catalytic / Fluoroolefins

1,2-Epoxyperfluorocyclohexane was obtained with a high yield by the epoxidation of perfluorocyclohexene with an aqueous solution of sodium hypochlorite in the presence of acetonitrile. 1,2-Epoxyperfluorocyclohexane undergoes both nucleophilic and electrop
