摘要
以双(三甲基硅基)氨基锂为起始原料,分别与氯化亚砜、三溴化磷反应,合成了双(三甲基硅基)硫二亚胺和双(三甲基)硅胺基-三甲基硅亚氨基磷,然后通过两者间的硫原子迁移反应,合成了标题化合物。通过梯度温度下的减压冷凝,实现了目标化合物的分离和纯化,并采用核磁共振、紫外-可见吸收光谱进行了结构表征,根据最大吸收波长计算得其跃迁能为2.53×10^(-19)J。
Bis（trimethylsilyl）diimine was synthesized by sulfur atom migration between bis（trimethylsilyl）sulfurdiimide and bis（trimethylsilyl）amino-（trimethylsilylimino）phosphin,which were synthesized via reaction of lithium bis（trimethylsilyl）amide with sulfinyl chloride and phosphorus tribromide,respectively.Bis（trimethylsilyl）diimine was separated from the reaction mixture by condensation at high vacuum,the structure of which was characterized by ^1HNMR and UV-Vis absorption spectra.The energy gap of bis（trimethylsilyl）diimine was calculated to be 2.53×10^-19J based on the maximum absorption wavelength.
