“…One of the most widely studied complexes is (R, R)-(-)-N, N -bis(3,5-di-tert-butylsalicylidene)-1,2-cyclohexanediaminomanganese(III) chloride called Jacobsen's catalyst [1][2][3]. Attempts have been made to immobilize this complex not only for the possibility to reuse but also to preclude deactivation [4,5]. These two characteristics are among the observed advantages of the heterogenized homogeneous complexes [6][7][8].…”

“…En este último caso, el encapsulamiento se puede llevar a cabo generando la macromolécula en la cavidad a partir de sus componentes, de la misma manera que se construye un barco dentro de una botella. A modo de ejemplo podríamos citar el encapsulamiento de un complejo de metal de transición quiral (Salen de Mn (III) en las cajas de la zeolita Y (véase Figura 3) o de zeolita EMT (30,31).…”

“…[137] Similarly, Mn-salen complexes have been formed inside zeolite cavities and have been shown to be selective epoxidation catalysts. [138,139] To avoid the limitations of the small apertures and cavities provided by zeolites, mesopores have been created inside zeolites X, Y and DAY. [140] By dealumination of the zeolite structure, mesoporous regions that are completely surrounded by micropores were obtained, and these intrazeolitic cavities were then used as the space in which to assemble metal complexes.…”
