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.
杂芳基硅烷可以通过杂芳族化合物与三有机乙烯基硅烷在 Ru3(CO)12 催化剂的帮助下反应合成。多种杂芳族化合物可用于这种 C–H/SiR3 偶联。在杂芳族化合物的情况下,观察到偶联反应发生在定向羰基的β位,例如酮、酯和酰胺。
