Copper-catalyzed arylation of oxadiamines and polyamines aimed at the synthesis of N,N′-diaryl derivatives using bromo- and iodoarenes was studied. Conversion of the starting compounds, selectivity of the arylation of primary amino groups in the presence of the secondary amino groups, and the yields of target products were shown to be strongly dependent on the nature of the oxadiamines and polyamines
研究了铜催化的氧二胺和多胺芳基化反应,旨在使用溴代芳烃和碘代芳烃合成 N,N'-二芳基衍生物。起始化合物的转化率、在仲氨基存在下伯氨基芳基化的选择性以及目标产物的产率被证明强烈依赖于氧二胺和多胺、芳基卤化物和卤原子的性质,以及反应条件,如配体、溶剂和所用的碱。为每种类型的起始胺和芳基卤化物找到了可靠的催化系统,可提供最高可能的 N,N'-二芳基化产物产率 (65-96%)。
