Abstract

Reactions of the silylene Si[(NCH2Bu(t))2C6H4-1,2], [Si(NN)], with NaOMe, excess Na or 1/3 Na yield the X-ray-characterised crystalline compounds [Na(micro-Si(NN)OMe)(THF)(OEt2)]2 (2b), [Na(THF)2Si(NN)]2 (3) and [Na(THF)4][(Si(NN))3-c] (4).

摘要

硅烯Si[(NCH2Bu(t))2C6H4-1,2]，即[Si(NN)]，与甲氧基钠、过量钠或1/3钠反应，生成经X射线表征的晶体化合物[Na(μ-Si(NN)OMe)(THF)(OEt2)]2（2b）、[Na(THF)2Si(NN)]2（3）和[Na(THF)4][(Si(NN))3-c]（4）。
