2,3,3,3 method for producing tetrafluoropropene

Disclosed is can cope with industrial scale, to provide a method of manufacturing a simple and efficient 2,3,3,3-tetrafluoropropene (HFC-1234yf). A 2,3,3,3 a (Wherein, X represents a Cl, Br or I.) In with a base is reacted to the compound represented by the general formula (2): CF (Wherein, X is as defined above.) Process steps, and (II) a compound represented by the general formula (2), to produce the 2,3,3,3 and reduced with hydrogen under the presence of a catalyst to produce a compound represented by the method, which comprises a. .BACKGROUND
