  Sulfonyl azides have been widely used as sulfonamido, diazo, and azido donors, as well as all-nitrogen 1,3-dipoles donors in synthetic chemistry. Here, the sulfonyl azides were used as efficient sulfonyl donors, which is very unusual. Trifluoromethanesulfonic acid-induced formation of the sulfonyl cation reactive species from sulfonyl azides was developed and used for the first time to couple various

  磺酰叠氮化物已被广泛用作合成化学中的磺酰氨基，重氮和叠氮基供体，以及全氮1,3-偶极供体。在这里，磺酰叠氮化物被用作有效的磺酰供体，这是非常不寻常的。研究了三氟甲磺酸诱导的由磺酰叠氮化物形成的磺酰阳离子反应性物质，并首次用于偶联各种灭活的芳烃，从而在环境温度下制备砜。

  D-Glucosamine is reported for the first time as a green ligand for copper catalyzed coupling of aryl halides and sodium sulfinates, which provides a simple and extremely efficient new route to unsymmetrical diaryl sulfones. The catalytic reaction proceeded in DMSO–H2O at 100 °C and gave a variety of aryl sulfones in high yields. The high water solubility of the ligand enables easy catalyst removal

  首次报道了D-葡萄糖胺作为绿色的配体，用于铜催化的芳基卤化物和亚磺酸钠的偶联，为非对称二芳基砜提供了一种简单且极为有效的新途径。催化反应在DMSO–H 2 O中于100°C进行，并以高收率得到了各种芳基砜。配体的高水溶性使其易于去除催化剂。该方法的范围通过市售药物zolimidine（用于消化性溃疡的药物）的一步合成进行验证，产率为65％。

  couple: Catalysts generated from Pd(OAc)2 and indolylphosphine ligands are highly effective in the titanium‐mediated coupling of aryl halides. Catalyst loadings as low as 0.05 mol % Pd can be used. The mild reaction conditions also allow the coupling of aryl sulfonyl chlorides with aryl titanium reagents to generate diaryl sulfones.

  它们构成了很好的一对：由Pd（OAc）2和吲哚基膦配体生成的催化剂在钛介导的芳基卤化物偶联中非常有效。可以使用低至0.05 mol％Pd的催化剂负载量。温和的反应条件还使芳基磺酰氯与芳基钛试剂偶合生成二芳基砜。
