本文发展了一种在水相中借氢环化铱配合物催化胺与醇的N-烷基化反应的方法。使用水作为绿色和生态友好的溶剂,环化铱催化剂介导的胺与醇的N-烷基化在宽范围的底物(多达46个实例)中显示出高活性(S/C高达10,000,产率高达96%)和胺/亚胺比(高达>99:1)。最重要的是,这种转化简单、有效,并且可以在克级进行,展示了其在工业合成N-烷基胺化合物方面的潜力。
This paper develops a methodology for cyclometalated iridium complex-catalyzed N-alkylation of amines with alcohols via borrowing hydrogen in the aqueous phase. The cyclometalated iridium catalyst-mediated N-alkylation of amines with alcohols displays high activity (S/C up to 10,000 and yield up to 96%) and ratio of amine/imine (up to >99:1) in a broad range of substrates (up to 46 examples) using water as the green and eco-friendly solvent. Most importantly, this transformation is simple, efficient, and can be performed at a gram scale, showcasing its potential for industrially synthesizing N-alkylamine compounds.
