Polymer-Supported Chiral Dirhodium(II) Complex for Asymmetric Reactions

(1)通过含铑（II）配合物的单体与苯乙烯和柔性交联剂的共聚反应，实现了铑（II）配合物的高效固定化。(2)聚合物负载的手性氟化二铑（II）络合物催化甲硅烷基烯醇醚与[N-（2-硝基苯磺酰基）亚氨基]苯基碘烷的胺化，以高产率提供具有高水平的对映选择性的氨基酮，并且可以使用多达20次，因为催化剂在固体反应物存在下容易地经受搅拌。(3)聚合物负载的手性氯化二铑（II）配合物促进分子间羰基叶立德环加成反应在CF 3C 6 H5在连续流动条件下，在那里实现了高产率以及高水平的对映选择性和周转数。

(1) A highly effective immobilization of Rh(II) complex has been achieved by copolymerization of dirhodium(II) complex-containing monomer with styrene and flexible cross-linker.(2) The polymer-supported chiral fluorinated dirhodium(II) complex catalyzed the amination of silyl enol ethers with [N-(2-nitrophenylsulfonyl)imino]phenyliodinane to provide amino ketones in high yields with high levels of enantioselectivity and could be used up to 20 times as the catalyst readily withstood stirring in the presence of the solid reactant.(3) The polymer-supported chiral chlorinated dirhodium(II) complex promoted intermolecular carbonyl ylide cycloaddition reactions in CF3C6H5 under continuous flow conditions, where high yields as well as high levels of enantioselectivity and turnover number were achieved.
