of the novel 1,2,3,4,5-tetrachalcogenagermolane Tbt(Tip)GeX4 (Tbt = 2,4,6-tris[bis(trimethylsilyl)methyl]phenyl, Tip = 2,4,6-triisopropylphenyl, X = S or Se) with 3 molar equiv of triphenylphosphine gave diaryl-substituted germanethione Tbt(Tip)GeS 1a and germaneselone Tbt(Tip)GeSe 2a as orange−yellow crystals and red crystals, respectively, which were unstable in air but thermally quite stable. Chalcogenation
合成了第一个动力学稳定的锗硫酮(锗-硫双键物种)和锗烷酮(锗-硒双键物种)。新型 1,2,3,4,5-四硫属元素格尔莫烷 Tbt(Tip)GeX4(Tbt = 2,4,6-三[双(三甲基甲硅烷基)甲基]苯基,Tip = 2,4,6-三异丙基苯基,X)的脱硫= S 或 Se) 与 3 摩尔当量的三苯基膦得到二芳基取代的锗硫酮 Tbt(Tip)GeS 1a 和锗烷硫酮 Tbt(Tip)GeSe 2a 分别为橙黄色晶体和红色晶体,它们在空气中不稳定但热稳定. 锗烯 Tbt(Dis)Ge 的硫氢化作用:导致分离出相应的锗烷硫酮 Tbt(Dis)GeS 1b 和锗烷硫酮 Tbt(Dis)GeSe 2b(Dis = 双(三甲基甲硅烷基)甲基)。锗烷硫酮 1a 和锗烷硫酮 2a 的分子结构,
