Palladium-Catalyzed Direct C2-Arylation of Benzo[ b ]thiophenes with Electron-Rich Aryl Halides: Facile Access to Thienoacene Derivatives

Direct coupling reaction of benzo[ b ]thiophene and electron-rich aryl bromides was achieved under Pd 2 (dba) 3 /SPhos catalysis in the presence of NaO t -Bu. The reaction system was applied for the installation of 2-(methylthio)phenyl group onto thiophene-fused polyaromatic molecules, demonstrating facile synthesis of precursors for thienoacene derivatives.

ORGANIC SEMICONDUCTOR DEVICE AND ITS PRODUCTION METHOD, AND COMPOUND

An organic semiconductor device which has an organic semiconductor layer formed by crystallizing a compound represented by the following formula (1) from a solution of the compound: wherein X1, X2 and X3 represent O, S, Se or Te; at least one of R1, R2, R3 and R4 represents a group that has both an aromatic ring to form a π-conjugated system with the skeleton to which it bonds, and a chainlike structure in which the number of the carbon atoms constituting the main chain is from 4 to 20, and the remaining ones represent a hydrogen atom or a substituent.
