The materials are characterized and the strength of the active sites is evaluated by in situ IR spectroscopy with cyclohexanone as a probe molecule. It is shown that besides isolated zirconium sites, zirconium-oxygen-zirconium species might also be active species for the rearrangement.Reserva de todos los derechosMEERWEIN-PONNDORF-VERLEYBAEYER-VILLIGER OXIDATIONSMETAL-ORGANIC FRAMEWORKSLEWIS-ACID CATALYSTSBETA ZEOLITESN-BETAHETEROGENEOUS CATALYSTSSELECTIVE CATALYSTCARBONYL-COMPOUNDSWATERQUIMICA INORGANICAQUIMICA ORGANICAArtículo10.1039/c3nj00551hCerrado1369-9261
