adamantoyl(tert-butylethynyl)bis(trimethylsilyl)silane (1b) was treated under the same conditions, 1-adamantyl-1-[(tert-butylethynyl)(trimethylsiloxy)(trimethylsilyl)]silyl-3,4-dimethylcyclopent-3-ene (2b) and 2-[(adamantyltrimethylsiloxymethyl)(tert-butylethynyl)(trimethylsilyl)]silylmethyl-3-methyl-1,3-butadiene (3b) were obtained in 24% and 3% yields. The reaction of 1a with diphenylacetylene at 160 °C afforded
制备了两个带有叔丁基乙炔基的酰基双(甲硅烷基)硅烷,并研究了它们的热行为。新戊酰基(叔丁基乙炔基)双(三甲基硅烷基)硅烷(1a)与2,3-二甲基丁二烯在密闭管中于160°C反应24小时,得到1-叔丁基-1-[(叔丁基乙炔基)(三甲基甲硅烷氧基)(三甲基甲硅烷基)]甲硅烷基-3,4-二甲基环戊-3-烯(2a)和2-[((叔丁基乙炔基)(叔丁基三甲基甲硅烷氧基甲基)(三甲基甲硅烷基)]甲硅烷基甲基-3-甲基-1,3-丁二烯(3a)的产率分别为45%和13%。当金刚烷基(叔丁基乙炔基)双(三甲基甲硅烷基)硅烷(1b)在相同条件下进行处理,1-金刚烷基-1-[(叔丁基乙炔基)(三甲基甲硅烷氧基)(三甲基甲硅烷基)]甲硅烷基-3,4-二甲基环戊-3-烯(2b)和2-[(金刚烷基三甲基甲硅烷氧基甲基)(以24%和3%的产率获得了叔丁基乙炔基)(三甲基甲硅烷基)]甲硅烷基甲基-3-甲基-1,3-丁二烯(
