Paragraph 0037; 0078; 0079, (2017/12/30)
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.

The hafnium hydride Cp*2HfH2 is reacted with a series of fluorocarbons to examine the scope of C-F bond activation. Aromatic, vinylic, and aliphatic C-F bonds all show some degree of reactivity, and possible mechanisms are discussed. Wiley-VCH Verlag GmbH & Co. KGaA, 2007.
