Carbonyl-Olefin/Alkyne Metathesis Reactions Catalyzed by Bifunctional H-USY Zeolites.

ABSTRACT: Metal-, organo-, and proton-catalyzed carbonyl-olefin/alkyne metathesis reactions have gained relevance in organic synthesis during the past decade, but their potential implementation in high-volume processes (i.e., in flow) is severely hampered by the lack of a general, robust, easily separable, and nontoxic solid catalyst. Both Brønsted and Lewis acid sites inside molecular-sized soluble cages seem to be involved during the catalytic process in solution; thus, a similar bifunctional acid solid catalyst, in a confined space, could play the desired catalytic role. We show here that commercially available, ultrastabilized aluminosilicate acid faujasites (H-USY zeolites), containing Brønsted and Lewis acid sites in microporous channels and cavities, catalyze a variety of intra- and intermole
