Abstract

NEW MATERIAL:A compound of formula I [Rf is perfluoroalkyl; Ar is (substituted) phenyl; A is perfluoroalkyl, alkyl, aryl, OH, alkoxyl, halogen or iodoniumoxy of formula II].
EXAMPLE: Di(trifluoroacetoxy)iodopentafluoroethane.
USE: A reagent for introducing a perfluoroalkyl group. For example, a perfluoroalkylthioalkylcarboxylic acid useful as a cephalosporin modifier can be obtained by reacting the compound of formula I with a mercapto compound.
PROCESS: A perfluoroalkyl iodide compound of the formula RfI is reacted with a trifluoroacetic anhydride in the presence of hydrogen peroxide in a concentration ≤40% to give a di(trifluoroacetoxy)iodine compound of formula III, which is then reacted with a (substituted) benzene of the formula ArH and a sulfonic acid derivative of the formula ASO3H to afford the compound of formula I.
