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
引入了一种新开发的含有酸和磷的水性体系,在该体系中,无味且稳定的芳基亚磺酸钠可以原位生成芳基亚硫基。这些自由基具有与炔烃,烯烃和H-膦氧化物反应的高反应性,以合成烷基硫化物和烯基硫化物以及硫代磷酸硫代酸酯。还进行了控制实验和量子计算,以深入了解芳基亚硫基自由基的生成机理。值得注意的是,该化学物质不含硫醇气味,有机溶剂和金属。
