Abstract
A convenient reaction of isoxazoles with an electrophilic fluorinating agent (Selectfluor) provides tertiary fluorinated carbonyl compounds under mild reaction conditions and with good functional group tolerance. Diverse transformations of the resulting α-fluorocyanoketones furnish a broad range of fluorinated compounds.
