The first 2-silaphosphetane was synthetized by reaction of butyllithium with a β-chlorosilylphosphine, followed by intramolecular cyclisation. Physicochemical data show the existence of an equilibrium between the monomeric form (2-silaphosphetane) and the dimeric form (2,6-disila-1,5-diphosphocane). Thermic decomposition under reduced pressure of the 2-dimethylsila-1-phenylphosphetane, through a β-elimination
通过使丁基锂与β-氯甲硅烷基膦反应,然后进行分子内环化,来合成第一个2-硅磷杂环丁烷。物理化学数据显示单体形式(2-silaphosphetane)与二聚体形式(2,6-disila-1,5-diphosphocane)之间存在平衡。在减压下通过β-消除过程对2-二甲基硅烷基-1-苯基膦进行热分解,生成了二甲基硅烷基苯基膦亚胺;这种具有SiP双键的新物种的特征在于形成了二聚体(Me 2 SiPPh)2,以及2-silaphosphetane插入SiP键中。
