The Stille cross-coupling reaction between a vinylcyclopropylstannane and iodobenzene or phenol triflate provides an expedious route to 1,2-phenylvinylcyclopropanes. However, similar coupling reactions using ortho-substituted aromatic substrates also lead to butylaromatic products, resulting from competitive sp³-sp² coupling reactions.
乙烯基环丙基锡烷与碘苯或三酸苯酚之间的 Stille 交叉偶联反应为 1,2-苯基乙烯基环丙烷提供了一条捷径。不过,使用正交取代的芳香族底物进行的类似偶联反应也会导致丁芳烃产物,这些产物来自竞争性 sp³-sp² 偶联反应。
