bond cleaving agent and arylsulfonyl oxime as an aldoxime precursor. The non‐acidic C−H bonds in various substances, including cycloalkanes, ethers, azacycles, and cyclic sulfides, were chemoselectively converted at ambient temperature under neutral conditions. The present transformation is a formal formylation of non‐acidic C(sp3)−H bonds in a single step.
使用光激发的4-苯甲酰基吡啶作为C(sp 3)-H键裂解剂和芳基磺酰基肟作为醛肟的前体,实现了光诱导的醛肟官能团向碳链的取代。各种物质(包括环烷烃,醚,氮杂环和环状硫化物)中的非酸性CH键在环境温度下于中性条件下进行化学选择性转化。目前的转变是一步完成非酸性C(sp 3)-H键的形式甲酰化反应。
