Using palladium(0)‐catalyzed coupling reactions we were able to synthesize mono‐, di‐, and trimeric porphyrins linked by di‐ and trivinylbenzenes. The reactions were carried out with palladium(II) acetate in DMF under phase‐transfer conditions. These coupling conditions are new in the field of porphyrin chemistry and proved to be a useful tool in the synthesis of C–C linked oligomeric porphyrins, as these compounds can be obtained in a simple one pot reaction with good yields.
