Selective fluorination of dichloromethane by highest oxidation state transition-metal oxide fluorides

Article abstract of DOI:10.1016/0022-1139(95)03353-X

In contrast to the reactivity of high oxidation state binary transition-metal fluorides with organic solvents, many transition-metal oxide fluorides do not react with CH₂Cl₂. Only the highest oxidation state species react, at temperatures below room temperature, via Cl-F exchange with > 90% selectivity, affording unstable high oxidation state chloro complexes which decompose to chlorine and lower oxidation state species.
