摘　　要：文章合成了一类规整的中孔材料SBA-15并用其作为支撑材料,然后通过3-氨基丙基三乙氧基硅烷作为偶联剂修饰得到了NH2-SBA-15,继而通过羟基硫胺的进一步修饰制备了新的非均相催化剂L2 (SM-SBA-15)。通过XRD, N2sorption, IR, NMR和TGA对材料结构和性能进行了表征。最后将键合的手性硫胺-L2作为非均相催化剂应用于非对称性共轭加成反应中,并对其性能进行了讨论。In the present work,we synthesized well-ordered mesoporous material SBA-15.By using it as support,NH2-SBA-15 was obtained by post-modification using 3-aminepropyltriethoxysilane(APTES).Furthermore a new heterogeneous catalyst L2(SMSBA-15),β-hydroxysulfoximin grafted on mesoporous NH2-SBA-15,was successfully prepared.This modified mesoporous materials have been fully characterized by XRD,N2sorption,IR,NMR and TGA techniques.Finally,the L2(SM-SBA-15) with covalently bond chiral sulfoximines waapplied on was applied on asymmetric conjugate additions and its performance is discussed.
