1,4-bis(triethyl-silyl)butadiyne at 250°C for 24 h afforded 1,1-dimesityl-3-silyl-2-silylethynyl-1-silacyclopropenes (3 and 5) and dimesitylbis(silylethynyl)silanes (4 and 6), respectively. The thermolysis of silacyclopropene 3 under the same conditions cleanly produced an isomerization produit 4.
1,1-二甲硅烷基-3-苯基-2-三甲基甲硅烷基-1-硅环丙烯(1)与1,4-双(三甲基甲硅烷基)-和1,4-双(三乙基甲硅烷基)丁二炔在250°C下共热解24小时分别得到1,1-二甲硅烷基-3-甲硅烷基-2-甲硅烷基乙炔基-1-硅环丙烯(3和5)和二甲硅烷基双(甲硅烷基乙炔基)硅烷(4和6)。在相同条件下硅环丙烯3的热分解干净地产生了异构化产物4。
