Abstract

Mn(II), Co(II), Ni(II) and Cu(II) and N,N-bis(3,5-di-tert-butylsalicyidene)-2,2-dimethyle-1,3-diaminopropane complexes have been synthesized in Y zeolite cavity by the reaction of ion-exchanged metal ions with the flexible ligand molecules. The host-guest materials obtained have been characterized by elemental analysis, XRD, surface area, pore volume, TGA, FT-IR and UV-Vis techniques. Analysis of data indicates that formation of complexes in the pores Yzeolite without affecting the zeolite framework structure. Also, we report the oxidation of cyclohexanol catalyzed by host-guest catalyst with tert-buthyl hydrogen peroxide as oxygen donor. The activity of benzyl alcohol oxidation decreases in the series- [Co(L)]/NaY > [Cu(L)]/NaY > [Mn(L)]/NaY > [Ni(L)]/NaY and the percent of product completely depend to catalyst. Zeolite complexes are stable enough to be reused and are suitable to be utilized as partial oxidation catalysts.
