Reactions of alkynes with arenes proceeded in the presence of dinuclear palladium complexes and trialkylboranes to yield alkyne hydroarylation products with high stereoselectivity. In the reactions of monosubstituted benzenes, meta and para products were formed in statistical ratios, while no ortho isomers were detected.
炔烃与芳烃的反应在双核钯配合物和三烷基硼烷的存在下进行,以产生具有高立体选择性的炔烃加氢芳基化产物。在单取代苯的反应中,间位和对位产物以统计比例形成,而没有检测到邻位异构体。
