Four 1,2-disilacycloalkanes of the formula , where n equals 3, 4, 5 and 6, have been prepared by two methods: one involves reaction of ClMe2SiSiMe2Cl with BrMg(CH2)nMgBr, the other comprises sodium/potassium condensation of ClMe2Si(CH2)nSiMe2Cl. It has been found that both the disilacyclopentane and -hexane exclusively undergo cleavage of the silicon—silicon bond when treated with concentrated sulfuric
已通过两种方法制备了四种化学式为n的3,4、5和6的1,2-二硅环烷烃:一种涉及ClMe 2 SiSiMe 2 Cl与BrMg(CH 2)n MgBr的反应,另一种包含钠ClMe 2 Si(CH 2)n SiMe 2 Cl的/钾缩合。已经发现,当用浓硫酸处理时,双硅环戊烷和-己烷都仅经历硅-硅键的断裂,而双硅环庚烷给出了其中硅-硅键未断裂的几种产物。当以0.6加热时,二硅环戊烷经历硅-硅键的裂解在乙醇中在90° N的乙醇钠溶液中溶解,而二硅环己烷在相同条件下非常稳定。
