2-Naphthalenyl ester fluorosulfuric acid is a diaryl fluorosulfate (diaryl-OSO2F). It can be synthesized with 99% yield from the reaction between phenol and sulfuryl fluoride in the presence of triethylamine. It undergoes Suzuki-Miyaura reaction with aryl boronic acid in the presence of Pd(OAc)2and Et3N to afford the corresponding biaryl derivative.The following aryl fluorosulfate can be utilized as a cross-coupling partner in Suzuki-Miyaura reactions. The standard reaction conditions for these palladium-catalyzed C-C bond formations are ligand-free and can be performed in water, at room temperature and are not air sensitive.
