A new method was developed for the direct synthesis of the second representative of the homologous series of diamond-like hydrocarbons, diamantane, in 65% yield by hydroisomerization of the norbornadiene dimer, -heptacyclo[8.4.0.0.0.0.0.0]tetradecane (binor-S) on treatment with concentrated sulfuric acid (98%). In the presence of HSO of lower concentration (75-80%), the reaction stops after the hydrogenation step giving -pentacyclo[7.3.1.1.1.0]tetradecane in 68% yield with excellent selectivity (100%).
开发了一种新方法，通过对降冰片二烯二聚体 - 庚环[8.4.0.0.0.0.0.0]十四烷（双环戊二烯）用浓硫酸（98%）进行加氢异构化反应，以65%的产率直接合成类金刚石烃同系物的第二个代表物金刚烷。在较低浓度（75 - 80%）的硫酸存在下，反应在氢化步骤后停止，以68%的产率和优异的选择性（100%）得到 - 五环[7.3.1.1.1.0]十四烷。
