A sulfur-iodine exchange protocol of diaryliodonium salts with inorganic sulfur salt was developed. Both aryl groups in the diaryliodonium salt were fully exerted in this transformation. Five- to eight-membered sulfur-containing heterocycles were achieved. Note that [1]benzothieno-[3,2-b][1]benzothiophene (BTBT) (an organic field-effect transistor (OFET) material) and Zaltoprofen were efficiently established through this method.
Diaryl thioether compound, and synthetic method and application thereof

Paragraph 0140-0142, (2018/02/04)
The invention discloses a diaryl thioether compound, and a synthetic method and an application thereof. Various diaryl thioether compounds can be obtained through a reaction of a reaction raw material high iodine salt in dimethyl sulfoxide at 60-100DEG C under the action of an odorless sulfuration reagent, an alkali, a metal catalyst and a ligand for 3-12h. Sulfur is introduced in the later stage, so poisoning of sulfur to the metal catalyst and incompatibility of an oxidant in the early stage reaction are 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 of the method is fully shown. The diaryl thioether compound prepared through the method can be further used to synthesize a photoelectric material BTBT and an anti-inflammatory drug zaltoprofen.

A new process has been developed for the palladium(ii)-catalyzed synthesis of dibenzothiophene derivatives via the cleavage of C-H and C-S bonds. In contrast to the existing methods for the synthesis of this scaffold by C-H functionalization, this new catalytic C-H/C-S coupling method does not require the presence of an external stoichiometric oxidant or reactive functionalities such as C-X or S-H, allowing its application to the synthesis of elaborate π-systems. Notably, the product-forming step of this reaction lies in an oxidative addition step rather than a reductive elimination step, making this reaction mechanistically uncommon.
