A method for converting 1, 3, 3, 3-tetrafluoropropene (HFO-1234ze) to 1-chloro-3, 3, 3-trifluoropropene (HCFC-1233zd) with high selectivity and without significant formation of 1, 1, 1, 3, 3-pentafluoropropane (HFC-245fa), by reacting 1234ze and hydrogen chloride (HCl) in a ...
Hence, the transformation of 4E to HCFO-1231xe may run via the consecutive HF-addition followed by HCl elimination processes, although the intermediate 1,1,2,3-tetrachloro-1-fluoropropane was not detected. However, observing the molecular structure, the group CCl2F of HCFO-1231xe can be ...
