  • HIGH-VALENT PALLADIUM FLUORIDE COMPLEXES AND USES THEREOF
    Publication number: 20140018538
    Abstract: The present invention provides novel high-valent palladium complexes. The complexes typically include multi-dentate ligands that stabilize the octahedral coordination sphere of the palladium(IV) atom. These complexes are useful in fluorinating organic compounds and preparing high-valent palladium fluoride complexes. The invention is particularly useful for fluorinating compounds with 19F for PET imaging.
