- A 5.6 and heterocyclic - hetero aromatic ring structure of synthetic method
-
The invention relates to a synthetic method of a fluorobenzoheterocycle-heteroaromatic ring structure. Specifically, according to the method, simple fluoro-substituted benzoheterocycle, a derivative of the fluoro-substituted benzoheterocycle and a heteroaromatic ring compound are taken as raw materials to prepare various fluoro-substituted benzoheterocycle-heteroaromatic ring compounds at a high yield by taking silver salt as an oxidant by the catalytic effect of palladium salt. By taking simple fluoro-substituted benzoheterocycle and the heteroaromatic ring compound as the raw materials, the method has the advantages of being low in amount of a used catalyst, wide in substrate application range, simple and convenient to operate, high in reaction efficiency and the like. The obtained fluoro-substituted benzoheterocycle-heteroaromatic ring building blocks have wide application in aspects of organic semiconductors, photoelectric materials and solar batteries.
