Abstract : Thermolysis of hexakis(2,6-diethylphenyl)cyclotristannane in xylenes at 200 C provides blue violet, crystalline 2,2,4,4,5,5-hexakis(2,6- diethylphenyl)pentastanna(1.1.1)propellane, 1, in 13% yield and hexakis(2,6- diethylphenyl)distannane, 2, after purification by column chromatography. Analytically pure 1 has been fully characterized by spectroscopic methods, including 119 Sn NMR, and a
摘要 : 六(2,6-二乙基苯基)环三锡烷在二甲苯中于 200 C 的热解得到蓝紫色结晶 2,2,4,4,5,5-六(2,6-二乙基苯基)五锡(1.1.1)推进烷, 1, 13% 产率和六(2,6-二乙基苯基)二锡烷, 2, 经柱层析纯化后。分析纯 1 已通过光谱方法(包括 119 Sn NMR)进行了充分表征,并且已对 1 和 2 的 2:1 混合晶体进行了晶体学分析。化合物 2 的 Sn-Sn 键长为 3.05 A,这是迄今为止观察到的聚锡烷最长的锡键长度(之前的最长值为 2.97 A)。
