Various C 3 ‐symmetric molecules were prepared by trimerization of acetyl aromatic compounds and subsequently coupled with various boronic acids under Pd 0 catalysis conditions to generate oligoaryl/‐heteroaryl C 3 ‐symmetric molecules. Several furan‐ and thiophene‐containing star‐shaped molecules were prepared by the use of Suzuki−Miyaura cross‐coupling as a key step. Structural and conformational details were explored by semi‐empirical molecular orbital theory using the AM1 method. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
