An efficient method involving a Pd/PCy3 catalyst in combination with a stoichiometric amount of Ag2CO3 has been established for the decarboxylative C[BOND]H bond arylation of thiophenes to give 2-arylthiophenes (see scheme; Cy=cyclohexyl). Electron-rich, electron-deficient, and heterocyclic benzoic acids can be used as the arylating reagent and a broad range of substituents on the thiophene are tolerated.
