Immobilized homogeneous catalysts

Although zeolite-encapsulated metal complexes were known for some time, the principle that such complexes could act as a new type of immobilized homogeneous catalysts was probably first demonstrated only in 1985 [37]. This achievement opened a new and fruitful area of research in immobilizing homogeneous catalysts. These catalysts are named appropriately ship-in-the-bottle (SIB) catalysts (see Fig. 42.5). General overviews of zeolite-encapsulated metal complexes were given [38, 39]. 

To improve the chances for the application of immobilized homogeneous catalysts the following obstacles have to be addressed (1) preparation of inexpensive chiral ligands with a suitable anchoring group (2) development of efficient and versatile immobilization methods and (3) better understanding of the interactions between supports and catalysts.
