High Oxidation State Binary Transition Metal Fluorides as Selective Fluorinating Agents

High oxidation state transition metal fluorides are selective fluorinating agents for dichloromethane, those with d0 electronic configurations undergo hydrogen-fluorine exchange and metal reduction, while dn species undergo chlorine-
