ChemInform Abstract: Reactions of Chlorine Fluorides and Oxyfluorides with the Nitrate Anion and Alkali-Metal Fluoride Catalyzed Decomposition of ClF5.

ChemInform Abstract

The binary chlorine fluorides ClFn (n = 1, 3, 5), when used in excess, undergo facile fluorine-oxygen exchange reactions with NO₃^- forming ClONO₂, unstable FClO, and FClO₂, resp., as the primary products. Whereas FClO₃ does not react with LiNO₃ up to 75 °C, FClO₂ reacts readily to give ClONO₂ and O₂ in high yield, probably via an unstable O₂ClONO₂ intermediate. The alkali metal fluorides CsF, RbF, and KF catalyze the decomposition of ClF₅ to ClF₃ and F2 which can result in a substantial F2 pressure at temp. as low as 25 °C.
