  Formamide CH bond activation has been achieved under oxidative conditions, using a copper catalyst and tert‐butyl hydroperoxide (TBHP) as the external oxidant (see scheme). This oxidative coupling of a range of dialkyl formamides provides an easy, phosgene‐free route for the selective synthesis of Z‐enol carbamates and 2‐carbonyl‐substituted phenol carbamates in high yields.

  使用铜催化剂和叔丁基氢过氧化物（TBHP）作为外部氧化剂，可以在氧化条件下实现甲酰胺CH键的活化（参见方案）。多种二烷基甲酰胺的这种氧化偶联为高产率地选择性合成Z-烯醇氨基甲酸酯和2-羰基取代的苯甲酸氨基甲酸酯提供了一种简单，无光气的途径。

  The catalytic activity of copper nanoparticles on charcoal (Cu/C) was investigated as an environmentally friendly heterogeneous catalyst for the synthesis of enol carbamates and amides via the oxidative coupling of N,N-dialkyl formamides with 1,3-dicarbonyl compounds and aromatic aldehydes with amine hydrochloride salts, respectively. Various enol carbamates and amides were synthesized in moderate to good yields using this method. Moreover, the catalyst could be recovered and subsequently reused in further reactions.

  Oxidative coupling of formamides with 1,3-dicarbonyl compounds to prepare enol carbamates was effected in the presence of CuO nanoparticles supported on alpha-Fe2O3-modified carbon nanotubes (CNTs@alpha-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. (C) 2013 Elsevier Ltd. All rights reserved.

  catalysed oxidative coupling reaction of formamides with β-keto esters and 2-carbonyl-substituted phenols successfully proceeded through direct C–H bond activation of formamides. The corresponding carbamates were formed with high stereoselectivity under mild reaction conditions. This protocol was successfully applied to the synthesis of three novel halogenated carbamates and a carbaryl insecticide derivative
