An efficient and convenient heterogeneous catalytic system has been developed for the aerobic cross-dehydrogenative coupling over NiGa layered double oxide (Ni3Ga-LDO) without any additives. The results indicated that the catalytic system could tolerate various tetrahydroquinoline derivatives and nucleophiles using molecular oxygen as a sustainable oxidant. The catalyst could be recycled four times
                                    已开发出一种高效便捷的非均相催化体系,用于在无任何添加剂的NiGa层状双氧化物(Ni 3 Ga-LDO)上进行好氧交叉脱氢偶联。结果表明,使用分子氧作为可持续氧化剂,该催化体系能够耐受各种
四氢喹啉衍
生物和亲核试剂。该催化剂可循环使用四次而不会显着降低活性或改变XRD谱图,表明Ni 3 Ga-LDO在交叉偶联反应中具有催化和结构稳定性。
