Herein we report the oxidative halogenation of thiols via the ex situ generation of chlorine by employing calcium hypochorite as solid bench-stable precursor. This approach enables the synthesis of three distinct classes of compounds (R-SF3, RSO2F and RSF4Cl). Metastable R-SF4Cl intermediates are further postfunctionalized to access structures of higher complexity, and computational analysis elucidate
在此,我们报道了使用次氯酸钙作为固体工作台稳定前体,通过异位产生氯来氧化卤化硫醇。这种方法能够合成三种不同类别的化合物(R-SF 3、RSO 2 F 和 RSF 4 Cl)。亚稳态 R-SF 4 Cl 中间体进一步后官能化以获得更复杂的结构,计算分析阐明了导致某些杂芳族 SF 4 Cl 结构顺式选择性的潜在途径。
