3-Haloindolizines were synthesized via Cu(II) halidemediated halogenation of indolizines. This C−H direct functionalization process occurred under mild conditions giving 3-haloindolizines in moderate to excellent yields, and the products obtained were tested under the Suzuki−Miyaura reaction providing 3-arylindolizines in high yields.

Pd‐catalyzed desulfitative approach to C‐3 arylation of indolizine derivatives has been developed, and the protocol uses readily available arylsulfonylchlorides as the arylation reagent under nitrogen. This transformation was performed in a mixed solvent of 1‐methyl‐2‐pyrrolidone and dimethoxyethane using simple triphenylphosphine as a ligand, which provides a new method for the C‐3 arylation of indolizines
