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.

Highly selective decarboxylative ortho-heteroarylation of aromatic carboxylic acids with various heteroarenes has been developed through Rh(III)-catalyzed two-fold C-H activation, which exhibits a wide substrate scope of both aromatic carboxylic acids and heteroarenes. The use of naturally occurring carboxylic acid as the directing group avoids troublesome extra steps for installation and removal of an external directing group.

supporting information; experimental part, p. 1641 - 1645 (2012/07/31)
The nickel-catalyzed cross-coupling reaction of arene- or heteroarenecarbonitriles with aryl- or heteroarylmanganese reagents via C-CN bond activation has been developed. Both electron-rich and electron-deficient nitriles can be employed as the electrophilic substrates. The reaction tolerates a range of functional groups and aromatic heterocycles. Copyright
