项目摘要

In this research project, we demonstrated an effective approach to Green and Sustainable Chemistry by designing heterogeneous metal catalysts using inorganic solids as macroligands, and found their outstanding catalytic performances for a variety of material transformations including selective oxidations, carbon-carbon bond-forming reactions, one-pot syntheses, dehalogenation, and fixation of carbon dioxide. Based on the unique properties of hydroxyapatite, montmorillonite, and hydrotalcite as advanced supports, various hybrid catalysts were created with respect to the target reactions.Catalytic systems incorporating the heterogeneous metal catalysts can offer significant benefits in achieving simple and clean organic transformations because they have the following advantages : (i)they allow the use of non-polluting oxidants, (ii)they possess high catalytic activity and selectivity, (iii)they have high substrate tolerance, (iv)they allow a simple work-up procedure and easy recovery of the catalyst, and (v)they are recyclable. By applying concepts from coordination chemistry, we have developed a preparation for nanostructured metal species that is much simpler than previous synthetic methods for solid-supported metal catalysts and provides a strong protocol for preparing catalytically active compounds that are uniform in composition and distribution on solid surfaces.
