The strategy of the synthesis of arylhydrazones via acceptorless dehydrogenative coupling of arylhydrazines with methanol was proposed and accomplished. In the presence of [Cp*Ir(2,2′-bpyO)(HO)] (0.5 mol %), a series of desirable products were obtained in high yields. It was found that functional groups in bpy are crucially important for the catalytic activity of iridium complexes. Furthermore, DFT
提出并实现了芳基肼与甲醇无受体脱氢偶联合成芳基腙的策略。在[Cp*Ir(2,2'-bpyO)(H2O)](0.5 mol%)存在下,以高产率获得了一系列理想的产物。研究发现,bpy 中的官能团对于铱配合物的催化活性至关重要。此外,还介绍了 DFT 计算和机械实验。值得注意的是,这项研究展示了直接使用甲醇代替甲醛或多聚甲醛进行有机合成的潜力。
