energy-transfer and electron-transfer processes generates an arene radical anion, which is subsequently trapped by hydrogen-atom transfer and finally protonated to form the dearomatized product. The photoreduction converts planar aromatic feedstock compounds into molecular skeletons that are of use in organic synthesis.
通过可见光照射直接还原
芳烃和杂
芳烃仍然具有挑战性,因为单个光子的能量不足以破坏芳香族的稳定性。本文显示两个可见光光子的能量积累允许
芳烃和杂
芳烃的脱芳构化。机理研究证实,能量转移和电子转移过程的结合产生
芳烃自由基阴离子,随后被氢原子转移捕获,最后质子化形成脱芳构化产物。光还原将平面芳香族原料化合物转化为可用于有机合成的分子骨架。
