Cationicruthenium 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

A rhodium(III)-catalyzed C–H/N–H bond functionalization for the synthesis of 1-aminoisoquinolines from aryl amidines and α-MsO/TsO/Cl ketones was achieved under mild reaction conditions. Thus, this approach provides a practical method for the site-selective synthesis of various synthetically valuable isoquinolines with wide functional group tolerance.
