The formation of silaferracyclopentanes, by the reaction of silacyclobutanes with iron carbonyls, is described and their properties and reactions are discussed. The parent complex, 2,2,2,2-tetracarbonyl-1,1 -dimethyl-1 -sila-2- ferracyclopentane, has been prepared by the reaction of Me2[graphic omitted]CH2 with [Fe(CO)9](the preferred route) or, under u.v. irradiation, with [Fe(CO)5] or [Fe3(CO)12];
描述了通过硅烷基环丁烷与羰基铁反应形成硅烷基环戊烷的过程,并讨论了它们的性质和反应。母体络合物2,2,2,2-四羰基-1,1-二甲基-1 -sila-2-亚铁环戊烷已通过Me 2 [CH2Cl2] CH 2与[Fe(CO)9 ](首选路线),或在uv照射下用[Fe(CO)5 ]或[Fe 3(CO)12 ]照射;它也由Na 2 [Fe(CO)4 ]和SiMe 2(CH 2 CH 2 CH 2Cl)Cl。描述了在硅上具有芳基,烷氧基或氯取代基的类似物,以及1,1,3,3-四甲基-1,3-二硅环丁烷和两个硅苯并环丁烯的衍生物。讨论了红外,1 H和13 C nmr以及质谱数据。硅烷四环戊烷的化学性质与母体硅环丁烷的化学性质形成对比。络合物SiMe 2)(CO)4显示出一些作为氢化硅烷化催化剂的活性。
