  • Synthesis ofC3-Symmetric Nano-Sized Polyaromatic Compounds by Trimerization and Suzuki−Miyaura Cross-Coupling Reactions
    作者:Sambasivarao Kotha、Dhurke Kashinath、Kakali Lahiri、Raghavan B. Sunoj
    DOI:10.1002/ejoc.200400257
    日期:2004.10
    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
