CATALYSTS, METHODS OF MAKING, AND METHODS OF HYDROFLUORINATION

Some embodiments of the invention include inventive catalysts (e.g., catalysts of Formula (I)). Other embodiments include compositions comprising the inventive catalysts. Some embodiments include methods of using the inventive catalysts (e.g., in hydrofluorination of an organic compound). Further embodiments include methods for making the inventive catalysts. Additional embodiments of the invention are also discussed herein.

Composition, fluorinating reagent, and method for producing fluorinated organic compound

An object of the present invention is to provide a method for producing a fluorinated organic compound with a high yield without using carbon tetrachloride in view of the fact that the production of a fluorinated organic compound with a sufficient yield was impossible for a hitherto-known method that uses a fluorinating agent that contains IF.sub.5-pyridine-HF alone. Another object of the present invention is to provide a fluorinating reagent that is capable of achieving this object. The present invention provides a composition comprising (1) IF.sub.5 and (2) an aprotic solvent (with the proviso that carbon tetrachloride is excluded), wherein the aprotic solvent is contained in an amount within a range of 50 mass ppm to 20 mass %.

Process for deoxyfluorination of phenols

The present invention refers to a process for transition-metal-assisted .sup.18F-deoxyfluorination of phenols. The transformation benefits from readily available phenols as starting materials, tolerance of moisture and ambient atmosphere, large substrate scope, and translatability to generate doses appropriate for positron emission tomography (PET) imaging.
