A fascinating Fe-promoted protocol for the synthesis of N-arylsulfonamides has been developed. Starting from commercially available nitroarenes and sulfonyl chlorides, moderate to excellent yields of the corresponding N-arylsulfonamides can be obtained. In particular, Fe dust was the sole reductant in the transformation and it can be easily performed on a large scale.
一种引人入胜的Fe促进的合成N-芳基磺酰胺的方案已经被开发出来。从商业上可得的硝基苯和磺酰氯出发,可以得到中等至极好的相应N-芳基磺酰胺的产率。特别是,Fe粉尘是转换中的唯一还原剂,且可以轻松地大规模进行。
