Footprint catalysis .5. Substituent effects of template molecules on the catalytic behavior of imprinted molecular footprint cavities.
Publication date: 1993
Journal: Bulletin of the Chemical Society of Japan
Abstract: ''Footprint catalysts'' are silica(alumina) gel catalysts with tailored substrate specificities; they are easily prepared by the present authors' molecular imprinting procedures with an appropriate template. Four footprint catalysts were newly prepared by imprinting using p-acetamido-substituted derivatives of benzenesulfonamide and benzamide as templates. They catalyzed transacylations of benzoic anhydride and 4-(acetamido)benzoic benzoic anhydride, respectively. The effects of the acetamido substituents apart from the reaction center on the substrate specificities were investigated
