Caesium Fluoroxysulphate as a Mild Fluorinating Agent for the Fluorination of Alkoxy-substituted Benzene and Naphthalene Derivatives

Article abstract of DOI:10.1039/c39810000148

Room-temperature fluorination of alkoxy-substituted benzene derivatives with caesium fluoroxysulphate in the presence of boron trifluoride as catalyst resulted in the formation of ortho- and para-fluoro-substituted products, the ratio being dependent on the size of the alkoxy-group, while reactions with 2-alkoxynaphthalene derivatives resulted in the formation of 1,1-difluoro-2-oxo-1,2-dihydronaphthalene as well as 1-fluoro-substituted products.
