Environmentally Friendly Catalysis using Supported Reagents: Enhanced Selectivity without Loss in Activity in the Alkylation of Benzene using Hexagonal Mesoporous Silica (HMS)-supported Aluminium Chloride†,1

Abstract

Substantial increases in selectivity towards monoalkylation of benzene with alkenes can be achieved through the use of mesoporous HMS as support for immobilised aluminium chloride and through the use of external site poisons while maintaining activities comparable to homogeneous AlCl₃.
