The FeCl3-mediated cyclization of α,α′-disubstituted Z-alkenes 1 is reported as a general and non-photochemical route to synthesize benzo[1,2-b:4,3-b′]dithiophene (BDT) derivatives 2, achievable in good yields starting from cheap and easily available materials. The influence of the temperature and the nature of the substituents on the scope and limitations of this methodology is also reported.
据报道,FeCl 3介导的α,α'-二取代的Z-烯烃1的环化是合成苯并[1,2- b:4,3- b ']二噻吩(BDT)衍生物2的一般和非光化学途径。可以从便宜且容易获得的材料开始以高收率实现。还报道了温度和取代基的性质对这种方法的范围和局限性的影响。

Process for the preparation of a benzoheterodiazole compound disubstituted with benzodithiophene groups which comprises reacting at least one disubstituted benzoheterodiazole compound with at least one monostannylated benzodithiophene compound.
Said benzoheterodiazole compound disubstituted with benzodithiophene groups can be advantageously used in the construction of luminescent solar concentrators (LSCs). Furthermore, said benzoheterodiazole compound disubstituted with benzodithiophene groups 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 both rigid and flexible supports. Furthermore, said benzoheterodiazole compound disubstituted with benzodithiophene groups can be advantageously used as precursor of monomeric units in the preparation of semiconductor polymers.

Compound comprising a benzoetherodiazole group of formula (I) and at least one benzodithiophene group or a mixture of compounds comprising a benzoetherodiazole group and at least one benzodithiophene group of formulae (II) and (III). Both said compound and said mixture of compounds can be advantageously used as spectrum converters in luminescent solar concentrators (LSCs), capable, in their turn, of enhancing the performances of solar devices (i.e. devices for exploiting solar energy) such as, for example, photovoltaic cells, photoelectrolytic cells.
