具有 1,3-二炔部分的硅系四炔经历连续的十六氢和四氢狄尔斯-阿尔德反应，得到一系列含有二苯并硅杂环骨架的稠合多环芳香族化合物。产物中的苯环充当1,3-二烯并与活性炔以及氧反应，提供[4+2]环加合物。
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.
