A series of tris (β-diketonato) zirconium (IV) complexes were immobilized into a synthetic
clay structure of Taeniolite by an ion-exchange method to generate organic/inorganic hybrid
compounds. The hybrid compound served as a good catalyst for ring-opening reactions of
methyl, ethyl, and dimethyl oxiranes with various alcohols to generate primary alkoxy
alcohols in appreciable selectivity. This method described a technique to immobilize cationic
zirconium complexes without losing selectivity.
