and green method for the selective synthesis of tertiary amines has been developed that involves iridium-catalyzed alkylation of various primary amines with aromatic or aliphatic alcohols. Notably, the catalytic protocol enables this transformation in the absence of additional base and solvent. Furthermore, the alkylation of nitrobenzene with primary alcohol to tertiary amine has also been achieved by
在此,已经开发了一种用于选择性合成叔胺的有效且绿色的方法,该方法涉及用芳族或脂族醇进行的铱催化的各种伯胺的烷基化。值得注意的是,催化方案能够在不存在额外的碱和溶剂的情况下实现这种转化。此外,硝基苯与伯醇烷基化为叔胺也已通过相同的催化体系实现。进行了氘标记实验和一系列对照实验,结果表明在烷基化过程中可能存在分子间借氢途径。
