can in situ generate arylsulfenyl radicals. These radicals have high reactivity to react with alkynes, alkenes, and H-phosphine oxides for the synthesis of alkyl and alkenyl sulfides and phosphonothioates. The control experiments and quantum calculations are also performed to gain insights into the generation mechanism of arylsulfenyl radicals. Notably, the chemistry is free of thiol odors, organic solvents

reaction of aryl bromides and iodides with aliphatic and aromatic thiols catalyzed by palladium complexes of the bisphosphine ligand CyPF-tBu (1) is reported. Reactions occur in excellent yields, broad scope, high tolerance of functional groups, and with turnover numbers that exceed those of previous catalysts by 2 or 3 orders of magnitude. These couplings of bromo- and iodoarenes are more efficient than
报道了由双膦配体 CyPF- t Bu ( 1 )的钯配合物催化的芳基溴化物和碘化物与脂肪族和芳香族硫醇的交叉偶联反应。反应以优异的产率、广泛的范围、高的官能团耐受性以及比以前催化剂高出 2 或 3 个数量级的周转数发生。这些溴代芳烃和碘代芳烃的偶联比氯芳烃的相应反应更有效,并且可以在较少的催化剂负载和/或更温和的反应条件下进行。因此,以前在芳基氯偶联中报道的范围和官能团耐受性的限制现在得到了克服。
