Abstract
Active catalysts for the epoxidation of alkenes by tert-butyl hydroperoxide are provided by silasesquioxane titanium(IV) derivatives; a non-leaching catalyst, not prone to irreversible protic cleavage of its siloxy functions by the oxidizing agent, contains a terdentate silasesquioxane ligand.Keywords
