A magneticallyseparable graphitic carbon nitride nanocomposite (Fe3O4/g‐C3N4) as a catalyst for the three‐component condensation reactions of carbonyl compounds, amines and trimethylsilylcyanide was thoroughly investigated. The reaction of these three components was found to be efficient, economical and green and took place in the presence of a catalytic amount of the magneticallyseparable catalyst
磁可分离的石墨氮化碳纳米复合材料(Fe 3 O 4 / g-C 3 N 4)作为羰基化合物,胺和三甲基甲硅烷基氰化物三组分缩合反应的催化剂进行了深入研究。发现这三种组分的反应是高效,经济和绿色的,反应是在催化量的磁可分离催化剂存在下进行的,以良好至极佳的产率产生相应的α-氨基腈。使用扫描电子显微镜,能量色散X射线和傅立叶变换红外光谱对制备的纳米复合材料进行表征。还发现该纳米复合材料是可重复使用的,可以容易地回收并重复使用几次而其催化活性没有明显降低。
