α-Halo and pseudohalo ketones are used for the first time as C(sp3)-based electrophiles in transition-metal-catalyzed C-H activation and as oxidized alkyne equivalents in RhIII-catalyzed redox-neutral annulations to generate diverse N-heterocycles. This transformation is efficient and scalable. Due to the mild reaction conditions, a variety of functional groups could be tolerated. Who needs alkynes? α-Halo and pseudohalo ketones (as C(sp3)-based electrophiles) are utilized as oxidized alkyne equivalents in RhIII-catalyzed redox-neutral annulations to efficiently generate diverse N-heterocycles. Owing to the mild reaction conditions, a variety of functional groups are tolerated.
