We report a redox‐neutral formylation of aryl chlorides that proceeds through selective 2‐functionalization of 1,3‐dioxolane through nickel and photoredox catalysis. This scalable benchtop approach provides a distinct advantage over traditional reductive carbonylation in that no carbon monoxide, pressurized gas, or stoichiometric reductant is employed. The mild conditions give unprecedented scope from
我们报告了芳基氯化物的氧化还原中性甲酰化反应,该反应是通过镍和光氧化还原催化作用对1,3-二氧戊环进行选择性2官能化而进行的。这种可扩展的台式方法相对于传统的还原羰基化具有明显的优势,因为它不使用一氧化碳,加压气体或化学计量的还原剂。温和的条件为丰富而复杂的芳基氯原料提供了空前的应用范围。
