摘要：

In the presence of GaCl3, silylethyne reacted electrophilically with aromatic hydrocarbons to give beta-silylethenylated arenes. 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 degrees 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 discussed.
