摘　　要：Polystyrene supported TiCI4 （Ps-TiCI4） and polystyrene supported FeC13 （Ps-FeC13） were prepared by coordi- nating Lewis acids with polystyrene. The catalysts were characterized by TGA, BET, SEM, IR and pyri- dine-adsorbed IR. The loading of Ps-TiC14 and Ps-FeCI3 were 0.35 and 0.3 mmol.g-1 respectively. Both catalysts were found to be efficient for the tetrahydropyranylation and detetrahydropyranylation of various alcohols and phenols in different solvents. Two catalysts can be recovered and reused for five times with good activity.Polystyrene supported TiCI4 （Ps-TiCI4） and polystyrene supported FeC13 （Ps-FeC13） were prepared by coordi- nating Lewis acids with polystyrene.
