of Co(II) and two substrate molecules, bind to O2 and absorb visible light over a wide spectral range, triggering in situ oxidative decarboxylation to produce molecules containing the quinazolin-4(3H)-imine scaffold. These reactions employed glyoxylic acid and ketoacids as new building blocks, and good to excellent yields of the corresponding products were obtained under mild reaction conditions using
钴/光氧化还原协同催化是一种成熟的可见光光氧化还原催化技术。最近,Co(II)配合物在均相催化中的光敏性引起了科学家们的兴趣。在这项研究中,光敏 Co(II) 复合中间体旨在开发新的合成方法。这些中间体由 Co(II) 和两个底物分子组成,与 O 2结合并吸收宽光谱范围内的可见光,触发原位氧化脱羧生成含有 quinazolin-4(3 H)-亚胺支架。这些反应采用乙醛酸和酮酸作为新的结构单元,在温和的反应条件下,使用绿色且廉价的试剂和溶剂,获得了良好至优异的相应产物产率。这些结果很重要,因为钴基光敏中间体的设计将有助于建立利用可见光的新方法,从而导致有机合成的创新。
