Heteroarylsilanes can be synthesized by the reaction of heteroaromatic compounds with triorganovinylsilanes with the aid of a Ru3(CO)12-catalyst. A variety of heteroaromatic compounds can be used in this C–H/SiR3 coupling. The coupling reaction was observed to take place at a position β to the directing carbonyl group, e.g., ketone, ester, and amide, in the case of heteroaromatic compounds.

Reactions of dihalogenoquinones or dihalogenoquinoxalines with thioamides gave the corresponding 1,4‐dithiines in high yields. Many of polycyclic 1,4‐dithiin derivatives can be synthesized by the reactions of dihalogenoheterocycles with thioamides, and they are useful as pigments and functional materials for electro‐optical applications. Some of heteroaromatic‐1,4‐dithiins formed an intermolecular charge‐transfer (CT) complex with a π‐acceptor such as TCNQ, and they are useful as π‐donors for CT complex.
