redox-neutral sulfonylative coupling of boronic acids and ammonium salts to afford (hetero)aryl alkyl sulfones by using potassium metabisulfite has been realized. Various functional sulfones were obtained by using commercially available and air-stable CoCl2 in combination with phenanthroline ligand. In addition, various carbon based electrophiles, including diaryliodoniumsalts, heteroaryl halides, and

Arylsulfone groups play an important role in the synthesis of functionalized molecules. The acetonitrile-mediated three-componentreactions for arylsulfone synthesis were developed in the presence of a 0.00025 mol % palladium catalyst. Arylboronic acids reacted with potassium metabisulfite (K2S2O5) and benzyl bromide in the presence of LiF and a very low concentration of PdCl2 in acetonitrile solvents
芳基砜基团在功能化分子的合成中起着重要作用。乙腈介导的芳基砜合成三组分反应是在 0.00025 mol% 钯催化剂存在下开发的。芳基硼酸与焦亚硫酸钾 (K 2 S 2 O 5 ) 和苄基溴在存在 LiF 和极低浓度 PdCl 2的情况下,在乙腈溶剂中反应,以中等至良好的产率生成相应的苄基芳基砜。与K 2 S 2 O 5反应的各种芳基硼酸和碳亲电试剂在优化条件下生产所需的芳基砜。有人提出乙腈加速了芳基硼酸和 LiF 反应中芳基阴离子物质的产生。
