AbstractInorganic polymer, silica and alumina-supported polytrifluoromethanesulfosiloxane solid superacids (abbreviated as SiO2-Si-SCF3 and Al2O3-Si-SCF3), have been prepared. The acid strength of superacids is higher than that of 100% H2SO4. It was found that SiO2-Si-SCF3 and Al2O3-Si-SCF3 could catalyze Friedel-Crafts acylation of benzene and benzene derivatives with aroyl chlorides under relatively mild conditions. The yield could amount to 97.6% and 92.1% respectively. The yield and the isomer distribution of corresponding ketones were influenced by reaction temperature and reaction time. The catalysts have considerably high stability and can be reused repeatedly without any large changes in their catalytic activity. The reactions are very clean, with HCl as the only by-product escaping during the reaction. Copyright (C) 2003 John Wiley Sons, Ltd.
