Silicon-tethered tetraynes possessing a 1,3-diyne moiety underwent consecutive hexadehydro- and tetradehydro-Diels–Alder reactions to give a series of fused polycyclic aromatic compounds containing a dibenzosilole skeleton. The benzene ring in the product acted as a 1,3-diene and reacted with the active alkyne as well as oxygen to provide [4 + 2] cycloadducts.
具有1,3-二炔部分的硅链四炔通过连续的六氢和四氢-狄尔斯-阿尔德反应进行反应,得到一系列含有二苯并甲硅烷基骨架的稠合多环芳族化合物。产物中的苯环起1,3-二烯的作用,并与活性炔烃和氧反应生成[4 + 2]环加合物。
