Abstract
Covalently anchored Mn(II) salen complexes on mesoporous materials have been prepared by direct condensation of prefabricated Mn complex on the support or via ensembling step-wise salen entities on the support and subsequent complexation. The resultant anchored complexes have been compared with the immobilised Mn(II) salen complexes on mesoporous materials prepared by the process of cationic exchange of a Mn(II) salen complex for the epoxidation of styrene and cyclic olefins with different oxidizing agents such as PhIO and m-chloroperbenzoic acid. Both types of samples show comparable structures but the anchored complexes can be recycled with perbenzoic acid as oxidant.
