A photoredox benzyl activation was developed via formidable C(sp3)–C(sp3) bond dissociation of 1‐aryl acetone oxime esters, easily prepared from benzyl ketones. The generated benzyl cation coupling with diverse O‐ and N‐ nucleophiles successfully forged important benzyl ether and amines derivatives that are valuable in last‐stage functionalizations.
光氧化还原苄基活化是通过1-芳基丙酮肟酯的强C(sp 3)–C(sp 3)键解离作用而开发的,该酯易于从苄基酮制备。生成的苄基阳离子与各种O-和N-亲核试剂偶联成功地锻造了重要的苄基醚和胺衍生物,这些衍生物在最后阶段的功能化中很有价值。
