Bond activation in action: Unprecedented ruthenium‐catalyzed oxidative annulations of alkynes through cleavage of CH bonds set the stage for an efficient 1(2H)‐isoquinolone synthesis with ample scope (see scheme; tAm=tert‐amyl). Mechanisticstudies provided strong evidence for a rate‐limiting CH bond metalation through carboxylate assistance.
