Host (nanodimensional pores of zeolite Y)–guest (3,10-dialkyl-dibenzo-1,3,5,8,10,12-hexaazacyclotetradecane, [Ni(R 2Bzo 2[14]aneN 6)] 2+) nanocomposite materials: Synthesis, characterization and catalytic oxidation of cyclohexene

Abstract

Nanoscale microreactor containing “3,10-dialkyl-dibenzo-1,3,5,8,10,12-hexaazacyclotetradecane, [Ni(R 2Bzo 2[14]aneN 6)] 2+, R = H, Me, Et, Bu and benzyl” was successfully prepared by the in situ one-pot template synthesis (IOPTS) of formaldehyde and 1,2-phenylenediamine (1,2-phen) with alkyl and benzyl amine within the nanodimensional pores of zeolite-Y. The new host–guest nanocomposite materials “[Ni(R 2Bzo 2[14]aneN 6)] 2+–NaY” were characterized by several techniques: chemical analysis and spectroscopic methods (FT-IR, UV/Vis, XRD, BET, DRS) and then were used for oxidation of cyclohexene with molecular oxygen.
