The reaction proceeded via cationic species generated by the interaction of GaCl3 and silylethyne. High reactivity of the intermediate was demonstrated by the rapid reaction rate at −78 °C using close to the equimolar amount of the substrates. ipso-Substitution reaction took place with 1,2,3-trimethoxybenzene. Structures and properties of several organogallium compounds involved in the reactions are
在 GaCl3 存在下,甲硅烷基乙炔与芳烃发生亲电反应,得到 β-甲硅烷基乙烯化芳烃。该反应通过由 GaCl3 和甲硅烷基乙炔相互作用产生的阳离子物质进行。使用接近等摩尔量的底物,在 -78 °C 下的快速反应速率证明了中间体的高反应性。1,2,3-三甲氧基苯发生同位取代反应。讨论了参与反应的几种有机镓化合物的结构和性质。
