Abstract

Visible-light-promoted hydrocarboxylation of allenes with formate salt and CO₂ was developed for the first time using commercially available [Ir(ppy)₂(dtbbpy)]PF₆ as a photocatalyst. This strategy provides an efficient and practical method to access β,γ-unsaturated linear carboxylic acids in moderate yields with complete regioselectivity.
