tetrafluoride with 1,4-dioxan in anhydrous hydrogen fluoride in the presence of small additions of sulfur chlorides or chlorine results in the replacement of several hydrogen atoms in dioxan ring by fluorine atoms. Depending on various conditions, 2,3,3-trifluoro-1,4-dioxan, 2,3,3,5,6-pentafluoro-1,4-dioxans as well as 1,2,2,2,2-pentafluoroethyl ether can be obtained as major products in a good yield.
在少量添加氯化硫或氯的情况下,四氟化硫与1,4-二恶烷在无水氟化氢中的反应导致二恶烷环中的几个氢原子被氟原子取代。根据各种条件,2,3,3-三氟-1,4-二恶烷,2,3,3,5,6-五氟-1,4-二恶烷以及1,2,2,2,2-五氟乙基可以以高收率获得作为主要产物的醚。
