THE DANISHEFSKY HETERO DIELS-ALDER REACTION MEDIATED BY ORGANOLANTHANIDE-MODIFIED MESOPOROUS SILICATE MCM-41

Easeofseparation,recovery,andreuseability characterize the hybrid catalysts described by comparison with their molecular congeners [Ln(fod)3]. A novel grafting sequence involving an in situ silylation tailors the catalytically active interface for organic transformations of activated substrate molecules and prevents destabilization of labile product molecules.
