This paper reports that a combined Brønsted base (t-BuOLi/CsF or LiOCEt3/CsF) system mediates the 1,5-double-carboxylation of nonfused 2-alkylhetarenes at both the benzylic and δ-positions. A wide range of functional groups (OMe, F, Cl, CF3, OCF3, sulfide, CN, amide, ketone, or sulfone) are tolerated under the established reaction conditions.
