- aggregation title "Mesoporous phenolic resin catalysts and their use in asymmetric epoxidation and aldol reactions".
- aggregation abstract "Ordered mesoporous phenolic resins are an advanced class of ultra-stable mesoporous materials that offer potential applications in the field of catalysis. Two select examples of asymmetric catalysis will be presented. First, the Jacobsen catalyst N,N'-bis(3,5-di-tert-butylsalicylidene)-1,2-cyclohexanediaminomanganese (III) chloride is covalently immobilized and highly dispersed on mesoporous phenolic resins through a direct and simple procedure. This novel catalytic system shows high catalytic activity and excellent enantioselectivity in the asymmetric epoxidation of diline. The heterogeneized Jacobsen catalyst is demonstrated to be a re-usable and zero-leaching catalyst system. In a second example, the mesoporous phenolic resins were functionalized with sulphonic acid groups and acted as novel support for the non-covalent immobilization of a L-phenylalanine derived chiral diamine organocatalyst for asymmetric aldol reactions. The immobilization is established by an acid-base interaction between the sulphonic acid group and the amine function. The acidity and in particular the electronic withdrawing environment of the sulphonic acid groups influence enormously the catalytic performance of the non-covalent immobilized chiral diamine catalyst.".
