The compound can be used as a recyclable solid catalyst for the selective epoxidation of cyclooctene by tert-butylhydroperoxide. In the epoxidation of prochiral olefins such as trans-β-methylstyrene, the corresponding epoxide isomers are obtained with fairly good to excellent selectivity, albeit with low enantiomeric or diastereomeric excesses.
