Unsymmetrical diaryliodonium phenyltrifluoroborate salts: Synthesis, structure and fluorination

Résumé

The unprecedented reaction of organotrifluoroborates salts of unsymmetrical diaryliodoniums to give aryl fluorides is presented. This preliminary report describes the first synthesis of unsymmetrical diaryliodonium phenyltrifluoroborates along with an exemplary x-ray crystal structure, and explores their reactivity regarding the fluorination of the diaryliodonium cation. Fluorination was found to be chemoselective, providing exclusively hindered aryl fluoride products in moderate to good yields (up to 89%).
