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
