OXIDATION REACTIONS WITH HOF AND ADDUCTS OF HOF AND HF WITH ACETONITRILE

In acetonitrile solution HOF oxides CF3SSCF3 via CF3S(O)(n)SCF3 (n = 1 , 2) to yield [CF3S(O)2]2O. Analogously, CF3Se(O)OH and CF3SeX (X = Cl , Br) are oxidized via CF3Se(VI) intermediates to provide finally [CF3 Se(O)2]2O. With CH3CN at low temperatures HOF and HF form 1:1 adducts, whose structures have been elucidated by low-temperature X-ray struct ure analysis. Additional proof for the formation of CH3CN . HF in the liquid phase is provided.
