3-dimethyl-1,3-butadiene, isoprene or 1,3-cyclohexadiene. However, since 16 is formed as the main product even in the presence of an excess of these dienes, the cyclization of the lithiated precursor ClSiMe[Fe(CO)2Cp]-CH(CH2But)SiMe[Fe(CO)2Cp]CH(Li)CH2But must be regarded as an alternative route to 16. The crystal and molecular structure of 16 indicate a configuration of the bulky ring substituents. The disilacyclobutane
所述vinylsilyliron络合物的适宜的[Cp(CO)2的Fe] RSI(Cl)的CHCH 2 [R =我(1)中,Ph(2),卜吨(3),铁(CO)2的Cp(4) ]和[CP(CO)的2的Fe] MESI(CL)CMeCH 2(14作为silaethene衍生物的生成的前体已被研究)。起始化合物1至4和14可以从Me(Vi)SiCl 2,Ph(Vi)SiCl 2,HSiCl 3和MeSiCl 3获得。分别通过明智地结合已发布的程序。通过分析和光谱学研究以及与已知数据的比较,对它们进行了表征。所述SiC中间体的产生试图通过处理乙烯基甲硅烷铁络合物机智礼部吨在低温(-10℃)。只有具有1是平滑的反应与形成的观察到二聚体1,3-双(环戊二烯基dicarbonyliron)-1,3-二甲基-2,4-二新戊基-1,3- disilacyclobutane(16预期silaethene的)的[Cp
