The heterogenization of a titanium(IV) silsesquioxane complex in an MCM-41 molecular sieve, by tailoring the polarity of MCM-41, results in self-assembled materials (see the space-filling model on the right) that are active, truly heterogeneous, and recyclable catalysts for liquid-phase alkene epoxi

β¦ Synopsis
Solid acids, such as zeolites and clays, catalyse the provides a cleaner, better alternative to conventional Lewis and BrΓΈnsted acids, enabling a more facile workup of intramolecular hydroxyalkylation (cyclialkylation) of several arylalkyl epoxides in moderate to excellent conversions and reaction mixtures and, in several cases, better selectivities. selectivities. The use of solid acids in these cyclialkylations
