My professor did like the idea of bromination of thiophene-carbamate followed by suzuki recation as suggested by Rolnor (thanks for that Rolnor). But my professor wants me to do (or try) the reaction you can find in the attachment (using direct arylation). Now I have to find a procedure to couple thiophenes to each other using direct arylation. I can base myself on the direct arylation I have done previously but I can obviously not use exactly same conditions. I will do some research tomorrow but I have no acces to scifinder at home. Do you guys think it could work?
thank you in advance
