in C–S coupling. This mild and scalable protocol offers operational simplicity and exceptional functional group compatibility, including ketone, ester, amide, nitrile, and halides, that is vulnerable to organolithium or Grignard reagents. Additionally, the sulfinamides are conveniently converted to a variety of important S(VI) compounds, like sulfonamides, sulfonimidamides, and sulfonimidates, among
我们描述了一种有机光氧化还原催化的 sp 3 C-S 偶联,将N -亚磺胺与实验室稳定的烷基三氟硼酸盐作为潜在亲核对应物,高效地生成烷基亚磺酰胺。与传统有机金属试剂的双电子反应性相比,该催化方法报道了有机金属试剂与N-亚磺酰胺在C-S偶联中的单电子过程。这种温和且可扩展的方案提供了操作简单性和出色的官能团兼容性,包括酮、酯、酰胺、腈和卤化物,这些官能团容易受到有机锂或格氏试剂的影响。此外,亚磺酰胺可以方便地转化为各种重要的 S(VI) 化合物,如磺酰胺、磺酰亚胺和磺酰亚胺酯等。
