H2L was characterized by single-crystallographic X-ray analysis. Its Co(II) and Mn(III) complexes ([CoL] and [MnLCl]) were prepared and immobilized on 3-aminopropyltriethoxysilane functionalized silica gel. The immobilized materials were found to be efficient catalysts for epoxidation of styrene in the presence of tert-BuOOH in acetonitrile at 40 A degrees C. The catalysts can be reused several times without significant loss of performance.eninfo:eu-repo/semantics/closedAccessAntimicrobial ActivityMetal-ComplexesLigandsEpoxidationCopperOlefinsZincCrystal structure of an unsymmetrical Schiff base, immobilization of its cobalt and manganese complexes on a silica support, and catalytic studiesArticle38219920610.1007/s11243-012-9678-02-s2.0-84876492497Q2WOS:000316063600011Q3
