Abstract
Maghemite–copper oxide nanocomposite catalyzed oxidative coupling of formamides with β-dicarbonyl compounds in the presence of tert-butyl hydroperoxide as an oxidant to produce the corresponding enol carbamates in excellent yields (up to 92%) under the optimized conditions. The simple preparation and the ability to be recycled and magnetically separated are salient features of this catalytic system.

摘要
在叔丁基过氧化氢作为氧化剂的存在下,磁赤铁矿-铜氧化物纳米复合材料催化甲酰胺与β-二羰基化合物的氧化偶联,从而在优化的条件下以优异的收率(最高92%)产生相应的烯醇氨基甲酸酯。简单的制备以及再循环和磁性分离的能力是该催化系统的显着特征。
