Abstract
In this study, we have investigated the role of immobilized Ni(II) complexes with macrocyclic ligands of 1,8-dimethyl-1,3,6,8,10,13-hexaazacyclotetradecane (L) and 1,8-dibenzyl-1,3,6,8,10,13-hexaazacyclotetradecane (L′) within montmorillonite and MCM-41 as catalysts for epoxidation of cyclohexene, cyclopentene, norbornene, styrene and α-methylstyrene with tert-butylhydroperoxide (TBHP). The yield of epoxide in a given period depends mainly on the reaction rate of the complex with TBHP which is greatly affected by the alkene structure, ligand type and solid support. No desorption was observed during the course of reaction. Some mechanistic points will be presented in this article.
