The selective hydrodefluorination of hexafluoropropene to HFO-1234ze and HFO-1234yf can be achieved by reaction with simple group 13 hydrides of the form EH3 ? L (E=B, Al; L=SMe2, NMe3). The chemoselectivity varies depending on the nature of the group 13 element. A combination of experiments and DFT calculations show that competitive nucleophilic vinylic substitution and addition-elimination mechanisms involving hydroborated intermediates lead to complementary selectivities.

Paragraph 0072; 0073, (2020/01/24)
A method of producing a hydrofluoroolefin, wherein said method comprises: reacting a fluoroolefin with XZmH3-m●L, wherein X is a group III element, L is a nitrogen, phosphorus, oxygen or sulphur-based ligand, m is from 0 to 2, and Z is a halogen, and wherein the fluoroolefin is either a fully-fluorinated fluoroolefin, or a fluoroolefin that is fully-fluorinated except from one olefinic hydrogen.

In the present invention from a number 1, 2, 3, 3, 3 - pentafluoropropene (HFO provided 1225ye) hexafluoropropylene (HFP) method for bath a number [...] substrate. The upper index 2, 3, 3, 3 - 1, 2, 3, 3, 3 - pen hit [phul [phul] base oro pro pen phenolic resin foam which is very low it is a coolant 1234ze (HFO provided 1234yf) HFP H2S-free capacity as an intermediate of a hydrogenating catalyst 1, 1, 2, 3, 3, 3 - hexafluoropropane (HFC-a 236ea) is patterned to expose a hydrogen on generating; reacting a hydrogen fluoride catalyst obtained in said HFC provided 236ea and subjected to a high pressure liquid coolant bath of hydrogen fluoride in an HFO provided 1225ye number number 2000. Reacting a number when a HFC-a 236ea HFP hydrogen and vapor phase high pressure liquid coolant, reaction properly time to prevent the hydrogen consumed only unreacted hydrogen separation and circulating process can be eliminated, such as returning excess of hydrogen by a prefilled billion number. In hydrogenation of the resulting gaseous products another separation step (HFC-a 236ea) followed by a high pressure liquid coolant vapor reaction directly without a perhalogenated alkyl HFO provided 1225ye number 2000. In addition in the present invention HFP hydrogenation reaction temperature and number of stand-alone Dichlorethane efficiently number for the HFC-a 236ea perhalogenated reactions the method generates a control hydrogenation cycled in an HFC-a 236ea surfaces have diameters less than 2000.
