The formation of a new transient germa-alkyne Ar-GeC–SiMe3 [Ar = 2,4-di-tert-butyl-6-(diisopropylaminomethyl)phenyl] is achieved by photolysis of the corresponding trimethylsilyldiazomethylgermylene ArGeC(N2)SiMe3 (2). The germa-alkyne is characterized by trapping reactions with H2O and an equimolar mixture of tert-butanol and water. The respective adducts, the gem-germanediol 5 and the alkoxygermanol
通过光解相应的三甲基甲硅烷基重氮甲基锗亚芳基ArGeC(N 2)SiMe ,可以形成新的瞬态发芽炔烃Ar-Ge C-SiMe 3 [Ar = 2,4-二叔丁基-6-(二异丙基氨基甲基)苯基]。3(2)。炔烃炔的特征在于与H 2 O以及叔丁醇和水的等摩尔混合物发生捕集反应。各自的加合物,宝石-锗烷二醇5和烷氧基锗烷醇4已经通过光谱法充分表征。提出了对该机理的研究,在两种情况下,添加都涉及锗烷的瞬时形成。的结构通过单晶X射线衍射确定2和5。
