已经开发了纤维素负载的手性Rh纳米颗粒(NP)催化剂。已经开发了纤维素负载的手性Rh纳米颗粒(NP)催化剂。在手性二烯配体的存在下,Rh纳米粒子在纤维素上均匀分散,催化芳基硼酸与烯酮和烯酸酯的不对称1,4-加成反应,得到了高产率的对映选择性加成产物,且无金属浸出。手性NP系统的固态NMR分析直接表明Rh NP与纤维素上的手性配体之间的相互作用。这是使用多糖负载的手性金属纳米颗粒进行不对称碳-碳键形成反应的第一个例子。
Cellulose-supported chiral Rh nanoparticle (NP) catalysts have been developed. Cellulose-supported chiral Rh nanoparticle (NP) catalysts have been developed. The Rh NPs, which were well dispersed on cellulose, catalyzed the asymmetric 1,4-addition of arylboronic acids to enones and enoates, one of the representative asymmetric carbon–carbon bond-forming reactions, in the presence of chiral diene ligands, providing the corresponding adducts in high yields with outstanding enantioselectivities without metal leaching. The solid-state NMR analysis of the chiral NP system directly suggested interactions between the Rh NPs and the chiral ligand on cellulose. This is the first example of using polysaccharide-supported chiral metal nanoparticles for asymmetric carbon–carbon bond-forming reactions.
