Abstract

In this study, the efficient method was introduced for the preparation of copper-periodic mesoporous organosilica nanocomposites (Cu@MOS NCs) as a high performance heterogeneous nanocatalyst. Then the nanocomposite was characterized with various methods such as X-ray diffraction (XRD), BET analysis, SEM and EDS microscopy and thermogravimetric analysis (TGA). The Cu@MOS NC as nanocatalyst was applied for one-pot three component reactions of aromatic aldehydes, dimedone, and malononitrile for the effective and green synthesis of 2-amino-4H-benzo[b]pyran derivatives in high yields, with operational simplicity, environmental friendliness, wide applicability and reusability and easy recovery of the catalyst.

铜周期介孔有机硅纳米复合材料在水介质中高效合成2-氨基- 4h -苯并[b]吡喃。
本文介绍了一种高效制备铜-周期介孔有机二氧化硅纳米复合材料(Cu@MOS NCs)的方法,该材料是一种高性能的非均相纳米催化剂。然后用x射线衍射(XRD)、BET分析、SEM和EDS显微镜以及热重分析(TGA)等方法对纳米复合材料进行了表征。将Cu@MOS NC作为纳米催化剂应用于芳香族醛、二美酮和丙二腈的一锅三组分反应中,高效、绿色地合成了2-氨基- 4h -苯并[b]吡喃衍生物,具有操作简单、环境友好、适用性广、可重复使用、易于回收等优点。
