Heteroarylsilanes can be synthesized by the reaction of heteroaromatic compounds with triorganovinylsilanes with the aid of a Ru-3(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 beta to the directing carbonyl group, e.g., ketone, ester, and amide, in the case of heteroaromatic compounds.
