Palladium-Catalyzed Selective Fluorination of o-Carboranes
摘要:
A Pd(II)-catalyzed direct selective fluorination reaction of carboranes using a F+ reagent has been developed, leading to a series of polyfluorocarboranes in high isolated yields. The mechanism involving electrophilic B-H activation, oxidation of Pd(II) by F+ species, and reductive elimination is proposed.
