small building block of great interest for its use in the elaboration of symmetrical or unsymmetrical donor-acceptor π-conjugated molecules, for optoelectronic applications. Herein, a convenient, one-pot, two-component synthesis of this intermediate is reported, based upon palladium-catalysed, phosphine and additive-free, direct C-H arylation process. The synthesis is studied in depth to obtain optimum
