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 diaryliodonium salts, heteroaryl halides, and
钴催化:通过使用焦亚硫酸钾,已经实现了硼酸和铵盐的高效钴催化氧化还原-中性磺酰偶联以提供(杂)芳基烷基砜。通过使用市售且对空气稳定的CoCl 2与菲咯啉配体组合获得各种功能性砜。此外,各种碳基亲电试剂,包括二芳基碘盐、杂芳基卤化物和碳酸盐都是相容的。这种氧化还原中性催化转化无需额外碱即可顺利进行,并显示出广泛的官能团耐受性。
