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.
含有1,3 - 二炔部分的硅连接四炔经历连续的十六脱氢和十四脱氢狄尔斯 - 阿尔德反应,得到一系列含有二苯并硅杂环戊二烯骨架的稠合多环芳烃化合物。产物中的苯环作为1,3 - 二烯,与活性炔烃以及氧气反应生成[4 + 2]环加成物。
