report herein the development of a S atom transfer process using triethyl phosphite as the S atom acceptor that allows thiols to serve as precursors of C-centered radicals. A range of functionalized and electronically unbiased alkenes including those containing common heteroatom-based functional groups readily participate in this reductive coupling. This process is driven by the exchange of relatively
我们在此报告使用亚磷酸三乙酯作为S原子受体的S原子转移过程的发展,该过程允许硫醇充当C中心自由基的前体。包括含有常见的基于杂原子的官能团的烯烃在内的一系列官能化的和电子无偏的烯烃很容易参与该还原偶联。此过程是由相对较弱的脂肪族硫醇的S–H和C–S键交换为所形成产物的C–H,C–C和S–P键所驱动。
