粘土层间金属络合物催化剂及其分子识别催化作用

粘土的可膨胀的二维空间有助于将催化活性的金属络合物阳离子交换法和配位体交换法插入到粘土层间，因而易于制得粘土层间金属络合物催化剂，这是均相催化剂多相化的一种好方法，粘土层间金属络合物催化剂具有分子识别催化作用，择形选择性，立体选择性，区域选择性，本文论述了多种多相化催化剂上的对不对称加氢反尖，区域选择加氢反应，区域选择羰基化反应和空间选择芳基化反应，粘土层间金属络合物催化剂有高的活性和选择性，它可以与匀相金属络合物催化剂相媲美。

Clay-intercalated Metal Complex Catalysts and Their Molecular Recognition Catalysis

The expandable layers of clay provide useful two dimensional hosts which facilitate introduction of catalytical active metal complexes by cation exchange and ligand exchange methods. Intercalation of metal complexes into the interlamellar space of clay is an excellent method for homogeneous catalyst heterogenization. Clay intercalated metal complex catalysts display molecular recognizing catalysis, such as shape selectivity, steroselectivity, regioselectivity. The application of these heterogenized catalysts in the asymmetric hydrogenation, regioselective hydrogenation, regioselective carbonylation and steroselective arylation is described in this review. Clay intercalated metal complex catalysts exhibit sufficiently high activity and selectivity to make them competitive to the homogeneous catalysts.
