The reactions of reagent 1 with acetylenes leading to the alkenyl(aryl)iodonium triflates have been investigated. The results indicate that the very simple and efficient one-pot conversion of terminal alkynes into alkenyl(aryl)iodonium triflates described in this paper presents several advantages over the previously described procedure. The stereoselectivity of these reactions is discussed on the basis
已经研究了试剂1与乙炔导致烯基(芳基)碘鎓三氟甲磺酸酯的反应。结果表明,本文所述的末端炔烃非常简单有效的一锅转化为链烯基(芳基)碘鎓三氟甲磺酸酯比先前描述的方法具有多个优势。这些反应的立体选择性是根据包括IR,NMR光谱和X射线分析在内的物理化学证据进行讨论的。结果表明,这些反应伴随有抗加成反应,以中等至极好的收率得到(E)-[β-(三氟氧基)链烯基](芳基)碘鎓三氟甲磺酸酯。还讨论了一种可能的机制。
