Palladium-catalyzed coupling reactions, such as the Suzuki–Miyaura, Sonogashira, Stille, and Buchwald–Hartwig couplings, of phenols using nonafluorobutanesulfonyl fluoride (NfF) are described. These reactions proceeded through the in situ nonaflation of phenols.
Key words
phenol - cross-coupling - palladium - boronic acid - nonaflate
