An unprecedented electrochemical aromatic C–H oxygenation reaction for the synthesis of 4H-1,3-benzoxazines from easily available N-benzylamides is reported. These oxidative cyclization reactions proceed in a transition metal- and oxidizing reagent-free fashion and produce H2 as only theoretical byproduct. Adapting the C–H oxygenation reaction in an electrochemical microreactor has been demonstrated
据报道,从容易获得的N-苄基酰胺类化合物合成4 H -1,3-苯并恶嗪史无前例的电化学芳族CH氧化反应。这些氧化环化反应以无过渡金属和无氧化剂的方式进行,并仅作为理论副产物产生H 2。已经证明了在电化学微反应器中适应CH氧化反应。

Ring-opening iodination or bromination of unstrained cycloalkanols with NaI or NaBr and PhI(OAc)2 under visible light irradiation is developed. In this protocol the concentration of I2 is modulated through the generation of triiodide (I3-), thus significantly avoiding undesired side reactions. The reaction is under mild conditions and has a wide substrate scope, thus providing a practically useful
