A nickel catalyzed cross‐coupling protocol for the straightforward C−S bond formation has been developed. Various mercaptans and a wide range of ester and amide substrates bearing various substituents were tolerated in this process which afforded products in good to excellent yields. Furthermore, an intramolecular protocol for the synthesis of thioethers starting from thioesters has been developed
已经开发出一种镍催化的交叉偶联方案,用于直接形成C-S键。在该方法中可以耐受各种硫醇以及带有各种取代基的各种酯和酰胺底物,从而以良好或极好的收率提供产物。此外,已经开发了用于从硫代酯开始合成硫醚的分子内方案。该方案的效用已在苯并噻吩的新合成方案中得到证明。
