Thermoregulated phase-separable chiral Pt nanoparticle catalyst exhibited excellent ee (>99%) in the enantioselective hydrogenation of activated ketones for preparing chiral α-hydroxy acetals and chiral 1,2-diols. More importantly, the chiral catalyst could be easily separated by phase separation and directly reused in the next cycle without any loss in catalytic activity and enantioselectivity, even in the gram-scale reaction. The leaching of Pt was under the detection limit of the instrument.

高效和可回收的手性Pt纳米颗粒催化剂,用于活化酮的对映选择性加氢

在制备用于制备手性α-羟基缩醛和手性1,2-二醇的活性酮的对映选择性加氢反应中,可调节温度的可分离相的手性Pt纳米颗粒催化剂表现出优异的ee(> 99%)。更重要的是,手性催化剂可以容易地通过相分离而分离,并且可以在下一个循环中直接重复使用,即使在克级反应中,也没有任何催化活性和对映选择性的损失。Pt的浸出量低于仪器的检测极限。
