Title: | Chitin and Chitosan anchored methyltrioxorhenium: an innovative approach for selective heterogeneous catalytic epoxidations of olefins | Authors: | Di Giuseppe, Andrea Crucianelli, Marcello Passacantando, Maurizio Nisi, Stefano Saladino, Raffaele |
Keywords: | Chitin;Chitosan;Heterogeneous catalysis;Hydrogen peroxide;Methyltrioxorhenium;Olefin oxidation;Polysaccharide | Issue Date: | 2011 | Publisher: | Elsevier | Source: | Di Giuseppe, A. et al. 2010. Chitin and Chitosan anchored methyltrioxorhenium: an innovative approach for selective heterogeneous catalytic epoxidations of olefins. "Journal of Catalysis" 276(2): 411-422. | Abstract: | Novel complexes between methyltrioxorhenium (MTO) and natural polysaccharides like chitin and chitosan, or modified chitosan-bearing N-substituted acyl or alkyl pyridine moieties, were synthesized and used for the oxidation of alkenes, including acid-sensitive styrene derivatives, with urea hydrogen peroxide adduct (UHP) as primary oxidant. High conversions and yields of the corresponding epoxides were obtained. Silica-chitosan hybrid composites with increased surface area and mechanical properties were also prepared and used as MTO supports. A correlation on the role played by the different MTO-coordinating ligand sites of supports, on the experimental outcome of olefin catalytic oxidations, is discussed. |
