Recent remarkable success of copper-catalyzed oxidative bond formations led us to develop an environmentally benign copper-catalyzed sulfur–nitrogen bond-forming reaction to provide synthetically and industrially useful electron-deficient sulfenamides. The low nucleophilicity of N-formyl/acyl- and sulfonylamides was overcome by introducing a 1,5,7-triazabicyclo[4.4.0]dec-5-ene additive. A variety of
最近铜催化氧化键形成的显着成功使我们开发了一种环境友好的铜催化硫氮键形成反应,以提供合成和工业上有用的缺电子次磺酰胺。通过引入 1,5,7-三氮杂双环 [4.4.0]dec-5-烯添加剂,克服了 N-甲酰基/酰基-和磺酰胺的低亲核性。以良好的产率合成了多种 N-甲酰基/酰基亚磺酰胺和 -硫代磺酰胺,而硫不会过度氧化。相关的机理研究支持了所提出的反应机理。
