  A process for producing a crosslink-cyclized cyclopentadiene, comprising the steps of reacting a cyclopentenone with an alkali metal hydride to thereby reduce the cyclopentenone (reduction step A) into a cyclopentenol; and reacting the cyclopentenol with a dehydrating agent to thereby dehydrate the cyclopentenol (dehydration step B) into a crosslink-cyclized cyclopentadiene of the general formula (III): 1 wherein each of R 1 and R 2 independently represents a hydrogen atom or a linear or branched saturated alkyl group having 1 to 6 carbon atoms, n is an integer of 3 to 10, and the broken line in the 5-membered ring denotes that the 5-membered ring has two double bonds.

  一种生产交联环化环戊二烯的方法，包括以下步骤：将环戊酮与碱金属氢化物反应，从而还原环戊酮（还原步骤A）成为环戊醇；将环戊醇与脱水剂反应，从而脱水环戊醇（脱水步骤B）成为通式（III）的交联环化环戊二烯：其中，R1和R2各自独立地表示氢原子或具有1至6个碳原子的线性或支链饱和烷基，n是3至10的整数，5元环中的断裂线表示5元环有两个双键。
