Visible light-driven cross-coupling reactions of alkyl halides with phenylacetylene derivatives for C(sp3)–C(sp) bond formation catalyzed by a B12 complex

Author affiliations

Abstract

Visible light-driven cross-coupling reactions of alkyl halides with phenylacetylene and its derivatives catalyzed by the cobalamin derivative (B12) with the [Ir(dtbbpy)(ppy)2]PF6 photocatalyst at room temperature are reported. The robust B12 catalyst and Ir photocatalyst provided high turnover numbers of over 33 000 for the reactions.
