The N-methylation of amines with methanol in aqueous solution was proposed and accomplished by using a water-soluble metal-ligand bifunctional dinuclear iridium catalyst. In the presence of [(Cp*IrCl)2(thbpym)][Cl]2 (1 mol %), a range of desirable products were obtained in high yields under environmentally benign conditions. Notably, this research exhibited the potential of transition metal-catalyzed
提出了胺与甲醇在水溶液中的N-甲基化反应,并通过使用水溶性金属-配体双官能双核铱催化剂完成。在[(Cp * IrCl)2(thbpym)] [Cl] 2(1mol%)的存在下,在环境友好的条件下以高收率获得了一系列期望的产物。值得注意的是,这项研究显示了过渡金属催化的甲醇作为C1来源的潜在活化作用,用于在水溶液中构建CN键。
