我们报告了与游离芳烃环(C 6 H 6、C 6 Me 6和 C 7 H 8)弱结合的N-杂环亚甲硅烷稳定的单配位 Ag(I) 阳离子配合物的第一个例子。此外,已经研究了这些亲电 Ag(I) 配合物作为催化剂的应用,用于 A 3偶联反应,在无溶剂条件下以低催化剂负载量提供一系列炔丙胺,收率良好至极好(19 个实施例)。
We report the first examples of N-heterocyclic silylene-stabilized monocoordinate Ag(I) cationiccomplexes weakly bound to the free arene rings (C6H6, C6Me6, and C7H8). Further, the application of these electrophilic Ag(I) complexes as catalysts has been investigated toward A3-coupling reactions, which afforded a series of propargylamines in good to excellent yields with low catalyst loading under

Promoted by diethylazodicarboxylate, a novel and highly stereoselective synthesis of cis-beta-enaminones via oxidative dehydrogenation and hydration of the substituted propargylamines was realized. The possible mechanism was also proposed.
