Environmentally Friendly Chemistry Using Supported Reagent Catalysts: Chemically‐Modified Mesoporous Solid Catalysts

Chemically-modified mesoporous materials can be prepared as robust catalysts suitable for application in liquid phase processes such as Friedel-Crafts reactions, selective oxidations, nucleophilic substitutions and aromatic brominations.

Environmentally friendly catalysis using supported reagents: evolution of a highly active form of immobilised aluminium chloride

An entirely heterogeneous form of aluminium chloride that is highly active in the liquid-phase alkylation of aromatics using alkenes and chloroalkanes is prepared by treating porous support materials with AlCl3 in solution.

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

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.

Catalytic oxidation of organic substrates using alumina supported chromium and manganese

Supported reagents prepared by adsorption of chromium(VI) and manganese(VII) on alumina are capable of catalysing the aerial oxidation of organic substrates.
