methods of the hydrolysis of α, α, α, ω-tetrachloroalkanes. The reactions were carried out in fuming nitric acid, with the addition of nitrogen dioxide during the reaction or in the presence of a small amount of phosphoric anhydride. α, ω-Dichloroalkanes were derived from the ω-chloroalkanoic acids by the Kolbe electrolytic synthesis. Various other novel α, ω-disubstituted alkanes with very long methylene
通过改进的 α, α, α, ω-四氯烷烃的水解方法,以良好的产率(超过 90%)制备了比 ω-氯辛酸更高的 ω-氯烷酸。反应在发烟硝酸中进行,在反应过程中加入二氧化氮或在少量磷酸酐的存在下进行。α, ω-二氯烷烃通过 Kolbe 电解合成衍生自 ω-氯代链烷酸。还从四氯烷烃开始制备了各种其他具有很长亚甲基链的新型 α, ω-二取代烷烃,例如二醇、二腈、二羧酸和二胺。
