摘要：

Solid acid catalyst, bentonite-supported polytrifluoromethanesulfosiloxane (B-PTFMSS) has been for the first time prepared and used in the Friedel-Crafts acylation of ferrocene with various acyl chlorides. The catalytic activities were influenced by reaction time, reaction temperature, solvent and loaded amount of B-PTFMSS. It was found that the new catalyst B-PTFMSS possessed the advantages of high activities giving similar yield of aliphatic acyl ferrocene (>70%) as conventional Lewis acid catalyst aluminum chloride and it can be used repeatedly and easily regenerated. B-PTFMSS has also been characterized by IR spectra, pyridine adsorbed IR, specific surface area and XRD.
