Abstract

Polycyclic aromatic hydrocarbons (PAHs) are an emerging class of aromatic molecules in materials science. In their Communication on page 6551, K. Itami, K. Murakami et al. present the development of a palladium‐catalyzed annulative dimerization of phenylene triflate by twofold inter‐ and intramolecular C−H activation. This transformation forms two C−C bonds in one go, and thus enables the rapid synthesis of a variety of PAHs.
