The reaction of pentafluoro-lambda (6)-sulfanyl(SF5)-perfluoroalkyl iodides
with benzene is a convenient route for preparing SF5-perfluoroalkyl benzen
e derivatives, SF5(CF2)(n)C6H5 (n = 2, 4, 6, 8), a new class of perfluoroal
kylaromatic compounds. The preparation and characterization of these new ma
terials are described. (C) 2001 Elsevier Science B.V. All rights reserved.
