Development of Novel Heterogeneous Chiral Catalyst Using Functionalized Layered Hydroxy Double Salts

采用简单的阴离子交换法，原位制备了阴离子d -缬氨酸- pd （II）配合物插入到阴离子可交换的Ni-Zn混合碱盐（NiZn）中，并将其划分为层状羟基双盐。此外，一个Bronsted碱性PO_4^<3->阴离子也插入到NiZn层中，并与阴离子D-Valine-Pd配合物共存。合成的Bronsted碱性粘土- pd （II）纳米复合材料可有效催化多种醇的好氧氧化生成相应的醛类和酮类。

In-situ prepared anionic D-Valine-Pd(II) complex intercalated into the anion exchangeable Ni-Zn mixed basic salt (NiZn), which is classified by layered hydroxy double salts, was synthesized via simple anion exchange procedure. Furthermore, a Bronsted basic PO_4^<3-> anion was also intercalated into NiZn interlayer, coexisted with the anionic D-Valine-Pd complex. The synthesized Bronsted basic clay-Pd(II) nanocomposite catalyzed the aerobic oxidation of wide range of alcohols into the corresponding aldehydes and ketones effectively.
