氢化

In the asymmetric hydrogenation of ethyl pyruvate catalyzed by 0 5% Rh/PVP TiO 2, the chiral modifier cinchonidine not only induces the enantioselectivity, but also accelerates the reaction rate greatly.

研究了辛可尼定作手性修饰剂修饰的负载型纳米铑簇合物催化剂(0 5 %Rh/PVP TiO2 )催化丙酮酸乙酯不对称氢化反应，在该反应中手性修饰剂辛可尼定不仅具有对产物生成的手性诱导作用，而且对反应具有明显加速作用；在优化反应条件后，反应的TOF和对映选择性分别可以达到 5 8 0min-1和

As well as activity was exhibited. Theaddition of cinchonidine led to a remarkable increase in the reaction rate, as confirmed bythe IR study that the modifier activates the carbonyl groups of the reactant through itsquinuclidine nitrogen. On the contrary,〓 exerted a strong inhibition effect on theenantioselective hydrogenation. Chapter 3 Finely dispersed polyvinylpyrrolidone-stabilized iridium andbimetallic clusters were prepared by the alcohol-water reduction method.
