Reactivity of transition metal fluorides. Vi. Halogen-exchange reactions of vanadium pentafluoride

In an earlier paper in this series, it was indicated that halogen-exchange reactions between vanadium pentafluoride and covalent chlorides are very complex. The present work shows that the results may be rationalized on the basis of an initial halogen-exchange reaction, producing vanadium tetrachloride, chlorine, and the appropriate fluoride. As soon as some vanadium tetrachloride is formed, competitive reactions commence, thus making the exact elucidation of the reaction schemes very difficult. In order to clarify the situation, some reactions of vanadium tetrachloride itself were studied.
