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.

在本研究项目中，我们通过设计以无机固体为大配体的非均相金属催化剂，展示了绿色和可持续化学的有效途径，并发现它们在多种材料转化方面具有出色的催化性能，包括选择性氧化、碳-碳键形成反应、一锅合成、脱卤和二氧化碳固定。基于羟基磷灰石、蒙脱土和水滑石作为先进载体的独特性能，针对目标反应制备了各种杂化催化剂。含有非均相金属催化剂的催化系统可以在实现简单和清洁的有机转化方面提供显着的好处，因为它们具有以下优点：(i)它们允许使用无污染的氧化剂，（ii）它们具有高催化活性和选择性，（iii）它们具有高底物耐受性，（iv）它们允许简单的处理程序和催化剂的容易回收，以及(v)它们是可回收的。通过应用配位化学的概念，我们开发了一种纳米结构金属的制备方法，这种方法比以前的固体支撑金属催化剂的合成方法简单得多，并为制备在固体表面上组成和分布均匀的催化活性化合物提供了强有力的方案。
