A Ru-catalyzed, Cu-mediated site-selective, C3/C4-alkylation of N-pyridylisoquinolones is achieved. The reaction pathway is characterized by open-shell singlet and triplet energy pathways arising from the bimetallic complex. Regioselectivity arises from the energies of the two states. While the electron-donating groups primarily afford the unprecedented C(4)-isomer, electron-withdrawing groups show

金属配合物产生的开壳单线态和三线态能量途径。区域选择性源于两种状态的能量。虽然给电子基团主要提供前所未有的 C(4)-异构体,但吸电子基团显示出倾向于 C(3)-产物。
