Abstract

Polyureas derived from CO₂ and diamines were effective for C-H arylation of benzene in the presence of t-BuOK, producing biaryl products with various substituents in high yields up to 97%. Dual-activation of K⁺ and t-BuO^-, and π,π-stacking interaction between the substrate and the polymer backbone may account for the superior activity.
