Abstract. 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.

Keywords: β-alkoxyalcohols; oxiranes; ring-opening; Taeniolite; tris(β-diketonato)zirconium.
