A novel NaI-catalyzed oxidative amination of sodium sulfinates, employing both ethylenedibromide (EDB) and air as the oxidants, is described. EDB was first demonstrated to be a promising mild organic oxidant that in air, converted NaI into molecular iodine to promote the cross-coupling reactions of aromatic sodium sulfinates with amines to produce arylsulfonamides. Mechanistic studies indicated that
描述了一种使用二溴化乙烯 (EDB) 和空气作为氧化剂的新型 NaI 催化亚磺酸钠氧化胺化。EDB 首次被证明是一种有前途的温和有机氧化剂,它在空气中将 NaI 转化为分子碘,以促进芳族亚磺酸钠与胺的交叉偶联反应,生成芳基磺酰胺。机理研究表明,反应过程中可能涉及自由基途径。
Visible‐Light‐Induced Diradical‐Mediated

‐Cyclization towards Double Dearomative [2+2]‐Cycloaddition or Smiles‐Type Rearrangement
ipso-cyclization involving dearomatizing spiro-intermediates of aromatic compounds towards divergent reaction pathways deserves investigation but has been rarely reported so far. By tuning the rate of C−S bond cleavage in the key dearomatizing spiro intermediate, a chemical divergent reaction of (hetero)aryl sulfonamides has been achieved in a visible-light-induced energy transfer reaction pathway involving diradical
