The present invention aims to provide a simple and efficient method for producing butadiene compounds. The aforementioned problem is solved by a manufacturing method which is a method for manufacturing the compound represented by formula (1), [In the formula, R 1a , R 1b , R 2a , R 2b , R 3a and R 3b are the same or differently represent hydrogen, fluorine, alkyl, fluoroalkyl or aryl, but R 1a , R 1b , R At least one of 2a , R 2b , R 3a and R 3b represents fluoro or fluoroalkyl, or R 1a -CR 2a part, R 1b -CR 2b part, R 1a -C = CR 3a part and R 1b -C = One or more of the CR 3b parts may be the same or different to form a non-aromatic carbocyclic ring which may be substituted with one or more fluorine atoms; the single bond indicated by the wavy line indicates that the stereo configuration for the double bond to it is E Configuration or Z configuration, or a mixture of these in any ratio] is characterized by comprising the compound represented by formula (2a) and the compound represented by formula (2b) in: (1) metal catalyst, and (2) selected from ( a) Reduction of one or more of the group consisting of the transition metal element of the fourth period, (b) Group 12 metal element, (c) Group 13 metal element, (d) organic reducing agent and (e) carbon monoxide In the presence of the reagent, perform step A of the coupling reaction, [In the formula, X a represents chlorine, bromine or iodine, and other symbols represent the same meaning as above] [In the formula, X b represents chlorine, bromine or iodine, and other symbols represent the same meaning as described above]. |
