چکیده:

Transition metal/Y Zeolites were prepared by microwave solid state and aqueous solution ion exchange
methods. The activity of these Zeolites was investigated in a Diels-Alder reaction of Cyclopentadiene and
Maleic anhydride, Anthracene and Maleic anhydride.The yield of these reactions increased in order of
(NaY<Fe2+Y<Fe3+Y<MnY<CuY≈NiY<CoY≈CrY<ZnY) for both methods. The aqueous solution ionexchanged
Zeolites showed higher activity in comparison to solid-state exchange. About 65-70% yield was
observed for the Diels-Alder reaction with ZnY Zeolite. Endo-selectivity was observed for these reactions.
