simple approach for palladium-catalyzed C–H functionalization reactions utilizing an organophosphorus/sulfonate hypervalent iodine reagent as both an oxidant and the source of a functional group has been developed. Through this method, the oxidative phosphorylation-, sulfonation-, and hydroxylation of unactivated benzyl C(sp3)–H bonds, along with the hydroxylation and arylation of aryl C(sp2)–H bonds,
开发了一种新的且操作简单的方法,该方法利用有机磷/磺酸盐高价碘试剂作为氧化剂和官能团的来源,对钯催化的CH官能化反应进行了开发。通过这种方法,在温和的条件下成功地实现了未活化的苄基C(sp 3)-H键的氧化磷酸化,磺化和羟基化,以及芳基C(sp 2)-H键的羟基化和芳基化。具有出色的站点选择性。通用的C–OSO 2 R键为随后的多样化反应提供了平台。
