Abstract

Oxidative coupling of formamides with 1, 3-dicarbonyl compounds to prepare enol carbamates was effected in the presence of CuO nanoparticles supported on α-Fe2O3- modified carbon nanotubes (CNTs@ α-Fe2O3@ CuO) as an environmentally friendly heterogeneous catalyst. The simple preparation, and the ability to be recycled and magnetically separated are salient features of this catalytic system.
