Synthesis of hydrofluorocyclopentanes by vapor-phase catalytic hydrodehalogenation

Hydrofluorocyclopentanes (c5-HFCs) were prepared by gas-phase hydrodehalogenation of chlorofluorocyclopentenes (c5-CFOs) over various noble metals catalysts. The activity of the catalysts followed the order Pd > Pt > Rh > Ru, and the halogen atom on the C(sp2) atom exhibited stronger reactivity than the halogen on the C(sp3) atom. Possible mechanisms of the gas-phase hydrodehalogenation of c5-CFOs re proposed herein.

Method for preparing halogenated pentacyclic olefin by gas-phase isomerization reaction

The invention relates to a method for preparing halogenated pentacyclic olefin by gas-phase isomerization reaction. The method comprises the following steps of: by adopting the halogenated pentacyclic olefin C5HxFyClz as a material, under the existence of an isomerization catalyst, generating the gas-phase isomerization reaction to obtain isomers of the halogenated pentacyclic olefin, wherein X is an integer from 0 to 2, Y is an integer from 4 to 7, Z is an integer from 0 to 4, the sum of X and Y and Z is 8, and the isomerization catalyst is prepared by adopting at least one of lithium fluoride, potassium fluoride, sodium fluoride, rubidium fluoride or cesium fluoride as an active component and loading the active component on at least one of carriers such as aluminium fluoride, magnesium fluoride, iron fluoride, chromium fluoride and zinc fluoride. The method has the advantages that the material is easy to obtain, the isomerization catalyst is low in price, the yield of the isomer is higher, and the method is applicable to large-scale preparation of the isomers of the halogenated pentacyclic olefin by gas-phase reaction.
