European Journal of Organic Chemistry, EarlyView.A Pd(0)‐catalyzed cyclotrimerization of benzoCOTynes to form tri(benzo[8]annulenes) was developed. Three distinct isomers were isolated and structurally characterized by single‐crystal X‐ray diffraction. Ligand modulation proved crucial for enhancing regioselectivity: P(4‐OMePh), and (S)‐tBu‐Phox promoted the formation of the symmetric isomers.
