A copper-catalyzed sulfoxidation of benzylic C–H bonds by nondirected oxidative C(sp3)-H activation was developed. The process proceeds via sulfenate anions, which are generated by base-triggered elimination of β-sulfinyl esters and benzyl radicals. The functional group tolerance is high, and the product yields are good.
开发了铜催化的苄基CH键的无定向氧化C(sp 3)-H活化的硫氧化反应。该过程通过亚磺酸根阴离子进行,该亚磺酸根阴离子是通过碱触发的β-亚磺酰基酯和苄基基团的消除而产生的。官能团耐受性高,并且产物收率良好。
