ABSTRACT

Virtually all previously reported attempts at attaching homogeneous catalysts to a solid support have been concerned with making a solid ligand and then using this 'heterogeneous ligand' to prepare the active catalyst. Such an approach can require considerable synthetic efforts to produce the 'heterogeneous ligand' particularly if one wants to incorporate onto a solid one of the more complex chiral ligands in use today. Our approach to anchoring homogeneous catalysts involves the attachment of the homogeneous catalyst to the support using a beteropoly acid which interacts with both the support material and the metal atom of the complex.
