A novel enantiopure 1,2-diamine (5) having two phenolic hydroxy groups was attached into chloromethylated polystyrene through benzyl ether linkage, which was used as a chiral ligand of the catalyst in asymmetric hydrogenation of acetophenone.

core/shell support materials by compartmentalizing of Au(I)/Ru(II) catalysts has led to the formation of chiral alcohol derivatives from alkynes via sequential alkyne hydration and asymmetric transfer hydrogenation reactions. A Ru(II) complex was supported on chiral ligand end-capped amphiphilic ROMP polymers. The micellar Ru(II) catalyst was coated with a mesoporous silica shell to produce a secondary
通过Au( I )/Ru( II )催化剂的区室化利用有机/无机核/壳支撑材料,通过连续的炔水合和不对称转移氢化反应,由炔烃形成手性醇衍生物。 Ru( II )络合物负载在手性配体封端的两亲性ROMP聚合物上。胶束 Ru( II ) 催化剂涂有介孔二氧化硅壳,形成二级室,其中 IPrAuCl 配合物通过后孔径减小被限制在硅胶的介孔中。使用连续的炔水合/不对称转移氢化反应,在MeOH/H 2 O混合物中以高对映选择性将多种炔烃以定量产率转化为手性醇衍生物。
