A chiral composite material, derived from the deposition of a chiral nickel-diamine complex via wet impregnation to MCM-41, was shown to be an efficient heterogeneous catalyst for asymmetric 1,4-addition reactions of 1,3-dicarbonyl compounds with nitroalkenes, and of nitromethane with alkylidenemalonates. It was discovered that MCM-41 enhanced the reactivity and improved the stability of the chiral nickel complex that resides within the mesoporous material.
一种手性复合材料，通过湿浸渍法将手性镍二胺配合物沉积到MCM-41上制备而成，已证明其是一种高效的非均相催化剂，可用于1,3-二羰基化合物与硝基烯烃以及硝基甲烷与亚烷基丙二酸酯的不对称1,4-加成反应。研究发现，MCM-41提高了手性镍配合物的反应活性，并改善了其在介孔材料中的稳定性，该手性镍配合物存在于介孔材料中。
