The invention belongs to the technical field of preparation of pentafluoropropylene, and particularly relates to a method for preparing 1,2,3,3,3-pentafluoropropylene from hexafluoropropylene. According to the method, hexafluoropropylene and hydrogen are taken as raw materials, and 1,2,3,3,3-pentafluoropropylene is prepared through direct one-step reaction under the action of a solid mixture catalyst; the solid mixture catalyst is a mixture of one or more of oxyhalides of transition metals, IIA and IIIA group metals or derivatives thereof and a VIII group metal-based compound. Compared with amethod for preparing 1,2,3,3,3-pentafluoropropylene from hexafluoropropylene through a hydrogenation and HF removal two-step method, the solid mixture catalyst used in the method provided by the invention has higher pentafluoropropylene selectivity and reaction stability.

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.
