A Co(III)-catalyzed three-component coupling of C(sp2)–H bonds, alkynes, and halogenating agents to give alkenyl halides is reported. This transformation proceeds with high regio- and diastereoselectivity, and is effective for a broad range of aryl and alkyl terminal alkynes. Diverse C–H bond partners also exhibit good reactivity for a range of heteroaryl and aryl systems as well as synthetically useful secondary and tertiary amide, urea, and pyrazole directing groups. This multi-component transformation is also compatible with allenes in place of alkynes to furnish tetra-substituted alkenyl halides, showcasing the first halo-arylation of allenes. A convergent assembly of functionalized alkenyl halides is reported via Co(III)-catalyzed three-component C–H bond addition across alkynes and halogenating agents. The reaction proceeds with high regio- and diastereoselectivity and is effective for a wide range of alkynes and C–H bond substrates. Allenes are also suitable substrates for the preparation of tetra-substituted alkenyl halide products.
