Allylic sulfoxides, via [2,3]-sigmatropic rearrangement and oxidative addition of the resulting allylic sulfenate esters to Pd(0), are found to be excellent precursors of sulfenate anions. This hitherto unknown reactivity is applied in a new Pd(0)-catalyzed domino sequence involving sulfenate anion generation followed by arylation to afford aryl sulfoxides.
烯丙基亚砜通过[2,3]-σ重排和氧化生成的烯丙基亚磺酸酯到Pd(0)的氧化添加被发现是亚硫酸根阴离子的优良前体。迄今未知的反应性被应用于新的Pd(0)催化的多米诺骨牌序列中,该序列涉及亚硫酸盐阴离子的产生,然后芳基化生成芳基亚砜。
