摘要：

Various C_3-symmetric molecules were prepared by trimeriz-ation of acetyl aromatic compounds and subsequently coupled with various boronic acids under Pddeg 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-Miyauracross-coupling as a key step.Structural and conformational details were explored by semi-empirical molecular orbital theory using the AMI method.
