Macromolecular materials in heterogeneous catalysis: an aluminium silasesquioxane gel as active catalyst in Diels–Alder reactions of enones

A highly active, genuinely heterogeneous catalyst for liquid-phase Diels–Alder reactions of enones results from the silanol centred modification of an incompletely condensed silasesquioxane with trimethylaluminium, the resulting catalytic material being a gel that contains aluminium(III) siloxy functions (Al–O–Si) which are incorporated in a well defined, three-dimensional SiO framework.

Chapter 23:From ‘Nature’ to an Adventure in Single-Site Epoxidation Catalysis

Sir John Meurig Thomass research over the past 20 years has focused on the design, preparation and testing of new solid catalysts. He has been conspicuously successful in modifying nanoporous materials so as to place isolated, single-site active centres on their large internal areas. As such, it sh...
