Abstrakt: Various C3-symmetric molecules were prepared by trimerization of acetyl aromatic compounds and subsequently coupled with various boronic acids under Pd0 catalysis conditions to generate oligoaryl/-heteroaryl C3-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)
