摘要
Vanadium complexes of N-salicylidene-l-histidine immobilized on Al-MCM-41 designated as VO(Sal-His)/Al-MCM-41, were prepared and characterized by X-ray powder diffraction (XRD), FT-IR, nitrogen adsorption-desorption and chemical analysis techniques. VO(Sal-His)/Al-MCM-41 was found to catalyze the epoxidation of trans-2-hexen-1-ol, cinnamyl alcohol and geraniol with tert-butyl hydroperoxide (TBHP). The successful catalytic behavior of VO(Sal-His)/Al-MCM-41 with 99% conversion and excellent selectivity toward the corresponding epoxides is described herein.
