关于四(9-菲基)锡和二氯二(9-菲基)锡的合成研究

Preparation of tetraphenanthryl-(9)-tin and diphenanthryl-(9)-tin dichloride

我们在关于“二（9-菲基）锡”的研究中发现,虽然“菲基”有一个非常庞大的空间体积,但是出乎意料地是,菲的金属锡化合物却很容易形成。这一事实促使我们对Phen4Sn和Phen2SnCl2**合成进行了新的研究。结果,导致了在合成方法上的改进和简化。作者认为,这些方法学上的研究可以进一步推广到其它类似的稠环芳基锡化合物的合成上去。实验部分在以下的实验中,除了Phen4Sn同HCl反应外,都是在严格的氩气保护下进行的。测定IR采用Perkin-Elemer577红外光谱仪;元素分析采用Carlo Erba Elemental

Tetraphenanthryl-(9)-tin and diphenanthryl (9)-tin dichloride have been prepared by convenient methods. Their properties have also been described briefly. The experiments showed that good yield of Phen_4Sn has been attained by means of Grignard-synthesis and that analytically pure Phen_2SnCl_2 can be obtained by using thin layer chromatography to control the reaction.
