A highly efficient and mild palladium‐catalyzed cross‐coupling of sodium sulfinates and alkynes for the selective synthesis of unsymmetrical internal alkynes and vinyl sulfones has been developed. This methodology has advantages of easily accessible starting materials, functional group tolerance and a wide range of substrates, which provides rapid access to alkynes and vinyl sulfones.
已开发出一种高效,温和的钯催化亚磺酸钠和炔烃的交叉偶联剂,用于选择性合成不对称内部炔烃和乙烯基砜。这种方法的优点是容易获得起始原料,官能团耐受性和多种底物,从而可以快速获得炔烃和乙烯基砜。
