    名称:
    Epoxidation of Monomaleate with Hydrogen Peroxide Catalyzed by [π-C5H5N(CH2)15CH3]3PO4(WO3)4
    摘要:
    In the study, epoxidation of dodecanol monomaleate, hexadecanol monomaleate, and octadecanol monomaleate were carried out using [pi-C5H5N(CH2)(15)CH3](3)PO4(WO3)(4) as phase-transfer catalyst with 30% hydrogen peroxide as oxidant. The experimental results showed that [pi-C5H5N(CH2)(15)CH3](3)PO4(WO3)(4) had excellent catalytic effect on translating C-C double-bond into an epoxy group and had a good yield rate. The synthesized epoxides of decanol monomaleate, hexadecanol monomaleate, and octadecanol monomaleate have enormous potential application in organic synthesis, and they could be readily transformed into various synthetically useful intermediates or final products in many fields of chemistry.
