4,4,5,5,5-Pentafluoro-1-pentanol is prepared in a particularly advantageous manner from perfluoroethyl iodide by initially adding perfluoroethyl iodide in the presence of a radical initiator which does not carry any acyl groups to allyl alcohol and then hydrogenolytically dehalogenating the resulting 4,4,5,5,5-pentafluoro-2-iodo-1-pentanol in the presence of a catalyst, an acid binder and a diluent.
4,4,5,5,5-五氟-1-戊醇可以通过以下特别优越的方法从全氟乙基碘制备:首先在不带任何酰基的自由基引发剂的存在下将全氟乙基碘加入烯丙醇中,然后在催化剂、酸性结合剂和稀释剂的存在下氢解得到4,4,5,5,5-五氟-2-碘-1-戊醇。
