The formula: CF 3 CY = CX N H P wherein X and Y are independently hydrogen or a halogen selected from the group consisting of fluorine, chlorine, bromine and iodine; and N and P are independently an integer equal to 0, 1 or 2 under the condition (N + P) = 2) to prepare a hydropropene represented by the corresponding halopropane method. I will provide a. The method of the present invention comprises the formula: CF 3 C (YR 1 ) C (X N H PR 2 ) wherein at least one of R 1 , R 2 , X and Y is halogen And R 1 , R 2 , X and Y are independently hydrogen or fluorine under the condition that at least one hydrogen and one halogen are present on adjacent carbon atoms A halogen selected from chlorine, bromine and iodine) to a temperature at which dehydrohalogenation by thermal decomposition occurs, with or without the use of a catalyst.
