末端炔烃和乙烯基三氟甲磺酸酯之间的逐步钯催化交叉偶联得到了第一个由 3-亚烷基-1-丙炔基 [-C≡C-C(=CR2)-] 结构单元构建的交叉共轭烯炔大环，即扩展的轴烯 1 和杂化轴烯 2。
Stepwise palladium-catalyzed cross-coupling between terminal alkynes and vinyl triflates afforded the first cross-conjugated enyne macrocycles constructed of 3-alkylidene-1-propynyl [-C≡C-C(=CR2)-] building blocks, namely, the expanded radialene 1 and the hybrid radialene 2.
