The first Ru-catalyzed redox-neutral C–H activation reaction via N–N bond cleavage is reported. Pyrazolidin-3-one is demonstrated as an internally oxidative directing group that enables C–H annulation reactions with a broad scope of alkynes, including previously incompetent terminal alkynes. Pharmacologically privileged 3-(1H-indol-1-yl)propanamides were synthesized in high yields.
