Process for the preparation of a benzodithiophene compound which comprises reacting at least one monohalogenated dithiophene compound with at least one internal alkyne, in the presence of at least one catalyst containing palladium and of at least one co-catalyst containing copper in oxidation state +1.
Said benzodithiophene compound, after suitable functionalization and polymerization, can be advantageously used in the construction of photovoltaic devices (or solar devices) such as, for example, photovoltaic cells (or solar cells), photovoltaic modules (or solar modules), on either rigid and flexible supports. Furthermore, said benzodithiophene compound can be advantageously used as a constituent unit of luminescent solar concentrators (LSCS). Said benzodithiophene compound can also be advantageously used as a precursor of monomeric units in the preparation of semiconductor polymers.
