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.

The Fe3O4@EDTA-Cu(II) nanoparticles catalyzed oxidative coupling of formamides with β-dicarbonyl compounds is developed using tert-butyl hydroperoxide as an oxidant. In general, the enol carbamates are synthesized in excellent yields (up to 92%) under the optimized reaction conditions. Fe3O4@EDTA-Cu(II) has the advantage of being magnetically recoverable. Also, we have established a highly efficient Fe3O4@EDTA-Cu(II)-catalyzed tandem reaction of 2-iodoanilines with isothiocyanates for the synthesis of 2-aminobenzothiazoles.

The carbamate group is a key structural motif in many approved drugs and pro-drugs. There is increasing use of carbamates in the medicinal chemistry and agrochemical industry. We present, reagents and chemical methodologies for the synthesis of carbamates, and recent applications. The direct coupling of simple phenols with mono- and di-alkyl formamides provided the phenylcarbamate products.

Synthesis of enol carbamates was achieved via nickel-catalyzed oxidative coupling of formamides with 1,3-dicarbonyl compounds in the presence of tert-butyl hydroperoxide at 40?°C. Various derivatives of enol carbamates were synthesized by this method in good to excellent yields.

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 at 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.
