Nuclear magnetic resonance (n.m.r.) studies show that the exchange between fluorochromate(VI) and fluoride in dimethylsulfoxide is slow, in agreement with previous work on oxygen exchange between water and chromates(VI). No substitution was detected in the system CrO3F−/Cl− in acetonitrile. Mixtures of chromyl fluoride and chromyl chloride show rapid fluorine exchange, both as the pure compounds, and in solution in trichlorofluoromethane. Possible mechanistic implications of these results are discussed.
