A novel one-step direct reductive coupling reaction between nitroarenes and sodium arylsulfinates was realized in the presence of an inexpensive Pd/C catalyst. In this procedure, readily available nitroarenes are employed as the nitrogen sources, and sodium arylsulfinates serve as both coupling partners and reductants. The method features high efficiency by using cheap Pd/C with low catalyst loading and good functional group tolerance in the absence of any additional reductants or ligands. This facile and mild synthetic method enables the high efficiency synthesis of functionalized N-arylsulfonamides from readily available substrates.

通过Pd催化的硝基芳烃与芳基次磺酸钠的还原偶联反应合成N-芳基磺酰胺

在廉价的Pd / C催化剂的存在下，实现了硝基芳烃与芳基亚磺酸钠之间新颖的一步式直接还原偶联反应。在该方法中，将易得的硝基芳烃用作氮源，而芳基次磺酸钠既用作偶联配偶体又用作还原剂。该方法的特点是在不添加任何其他还原剂或配体的情况下，通过使用廉价的Pd / C，低催化剂负载量和良好的官能团耐受性来实现高效率。这种简便而温和的合成方法能够从容易获得的底物中高效合成官能化的N-芳基磺酰胺。
