Transition Metal Fluorides

Oxidation-reduction and halogen-exchange reactions of the higher fluorides of rhenium with a series of selected reagents have been investigated. The results correlate with studies of reactivities of higher fluorides of other transition metals previously reported. The reactions reported provide markedly improved preparative routes to the hexachloride, pentabromide, and pentafluoride of rhenium.

Following similar, previously reported studies of reactions of uranium hexafluoride, selected oxidation-reduction and halogen-exchange reactions of the tetra- fluoride, pentafluoride, and intermediate fluorides of uranium have been investigated.

Reaction Schemes

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.
