The invention discloses a synthesis method of diaryl ring fused sulfides represented by formula (B) and diaryl ring fused selenides represented by formula (C). The method is characterized in that a reaction of a reaction raw material high-iodine salt is carried out in dimethyl sulfoxide under the action of an inorganic sulfuration reagent or selenylation reagent and an alkali at 60-100 DEG C to obtain the diaryl ring fused sulfides and the diaryl ring fused selenides. Sulfur or selenium is introduced in the later stage in the presence of a nonmetal catalyst, so poisoning of sulfur to a metal catalyst in the early stage reaction is avoided; the above inorganic sulfur source is nontoxic and odorless; and two aryl groups in the high-iodine salt are fully used, so the atom economy and the greenness of the method are fully shown. The diaryl ring fused sulfides and the diaryl ring fused selenides prepared through the method can be applied to synthesize photoelectric materials BTBT and BTBS.

Using an easily prepared triethylammonium N-benzyldithiocarbamate salt as a sulfur source, a dual C?S functionalization of cyclic diaryliodoniums to form tricyclic thioheterocycles is realized. Our method uses the readily available copper sulfate to accelerate the chemical transformation under mild conditions. A broad range of cyclic diaryliodoniums with a ring size from 5- to 7-membered can be employed to gain a quick access to tricyclic thioheterocycles including dibenzothiophenes, thioxanthenes, and phenoxathiines.
