Amidocuprates, derived from organocopper reagents and lithium amides upon exposure to oxygen at low temperature, provide new amine derivatives in satisfactory yields. Details of this flexible and simple methodology are given. The reaction mechanism is analyzed in terms of an oxidative intramolecular coupling of aminyl radicals with the ligands on Cu in the intermediate amidocuprate. This reaction is
在低温下暴露于氧气时,衍生自有机铜试剂和酰胺化锂的酰胺基铜酸盐可提供令人满意的产率的新胺衍生物。给出了这种灵活而简单的方法的详细信息。根据胺基自由基与中间酰胺基铜酸盐中Cu上的配体的氧化性分子内偶联来分析反应机理。该反应是用于N-烷基化,-乙烯基化和-芳基化的温和而有效的方法,通过该方法可以合成许多不易通过常规途径获得的胺。一旦应用于酰肼锂,它也为N-取代的肼提供了新的直接途径。
