In recent years, silylene as an important active intermediate
has attracted much attention in various fields of
chemistry [1,2] and has led to a varied chemistry concerning
silylenes. A silylene reaction is regarded as an effective
method in the synthesis of new bonds and heterocyclic
compounds with Si, which has long been one of the most
interesting topics for organo-silicon chemists. The study
on saturated silylene has made good achievement [3–5],
There have been quite a lot of theoretical and experimental
investigations on addition reaction to silylene [6–12]. We
also have performed some studies on this aspect [13–16].
However, the above studies basically focus on addition
reaction to saturated silylene. For unsaturated silylene,
H2C@Si:, the simplest unsaturated silylene, was first
observed experimentally by Leclerq and Dubois [17]. Srinivas
et al. [18] have used neutralization–reionization mass

在近年来，硅烯作为一项重要的活性中间体
一直备受关注，在各个领域的
化学[ 1,2 ] ，并导致了不同的化学有关
silylenes 。 1硅烯反应被视为是一个有效的
法在合成新的债券和杂环
化合物与Si ，一直以来，其中一个最
有趣的主题为有机硅化学家。研究
对饱和硅烯取得了良好成绩， [ 3-5 ] ，
有相当多的理论和实验
调查的加成反应，以硅烯[ 6月12日] 。我们
也有演出，一些研究这方面的[ 13-16 ] 。
然而，上述研究基本上集中在除
反应饱和硅烯。为不饱和硅烯，
@ h2c硅： ，简单不饱和硅烯，首次
观察实验由leclerq和杜波依斯[ 17 ] 。 srinivas
等人。 [ 18 ]用中和reionization群众
光谱表明， h2c @斯：是一个可行的分子
在低气压气相。理论研究表明，
该地面国的不饱和硅烯是一种单
状态。能源的silaacetylene是84千焦/ mol的高于
这h2c @硅。因此， h2c @硅是最稳定的异构体
[ 19 ] 。在此外， grev等人。调查异构化
反应h2ge @ sih2很好[ 20 ] 。该项研究
对环加成反应的不饱和硅烯，我们
有选择环加成反应的甲基硅烯
和甲醛为模型反应，初步
探索反应机理的环加成反应
之间的不饱和silylenes和不对称
为P -保税化合物[ 21 ] 。在为了探索规则
的环加成反应之间的不饱和硅烯
和对称的P -保税化合物，甲基硅烯
和乙烯被选定为模型分子，其
机制被查处，并从理论上分析。
结果表明，这种反应有三种可能途径
