Cationic ruthenium complexes derived from KPF6 or AgOAc enabled efficient oxidative CH functionalizations on aryl and heteroaryl amidines. Thus, oxidative annulations of diversely decorated internal alkynes provided expedient access to 1‐aminoisoquinolines, while catalyzed CH activations with substituted acrylates gave rise to structurally novel 1‐iminoisoindolines. The powerful ruthenium(II) catalysts
从KPF来源的阳离子钌络合物6或AgOAc启用高效氧化Ç 上的芳基和杂芳基脒ħ官能化。因此,装饰多样的内部炔烃的氧化环化提供了通向1-氨基异喹啉的便捷途径,而取代丙烯酸酯催化的CH活化产生了结构上新颖的1-亚氨基异吲哚啉。强大的钌(II)催化剂显示出很高的位点,区域和化学选择性。因此,催化体系被证明可以耐受多种重要的亲电官能团。详细的机理研究为阳离子钌(II)催化剂通过简便,可逆的CH活化提供了有力的支持。
