| titleOfInvention | Method for producing butadiene compound |
| abstract | An object of the present invention is to provide a method for easily and efficiently producing a butadiene compound. The object can be achieved by a method for producing a compound represented by formula (1):wherein R<sup>1a</sup>, R<sup>1b</sup>, R<sup>2a</sup>, R<sup>2b</sup>, R<sup>3a</sup>, and R<sup>3b</sup>are the same or different, and each represent a hydrogen atom, a fluorine atom, an alkyl group, a fluoroalkyl group, or an aryl group;provided that at least one of R<sup>1a</sup>, R<sup>1b</sup>, R<sup>2a</sup>, R<sup>2b</sup>, R<sup>3a</sup>, and R<sup>3b</sup>represents a fluorine atom or a fluoroalkyl group; orone or more moieties among a R<sup>1a</sup>-C-R<sup>2a</sup>moiety, a R<sup>1b</sup>-C-R<sup>2b</sup>moiety, a R<sup>1a</sup>-C=C-R<sup>3a</sup>moiety, and a R<sup>1b</sup>-C=C-R<sup>3b</sup>moiety are the same or different, and each may form a non-aromatic carbon ring that may be substituted with one or more fluorine atoms; andeach single bond expressed by a wavy line shows that the configuration with respect to a double bond to which the single bond is bonded is E configuration, Z configuration, or a mixture thereof at any ratio;the method comprising step A of subjecting a compound represented by formula (2a):wherein X<sup>a</sup>represents a chlorine atom, a bromine atom, or an iodine atom, and the other symbols are as defined above, and a compound represented by formula (2b):wherein X<sup>b</sup>represents a chlorine atom, a bromine atom, or an iodine atom, and the other symbols are as defined above, to a coupling reaction in the presence of (1) a metal catalyst and (2) one or more reducing agents selected from the group consisting of (a) transition metal elements in the 4th period, (b) metal elements in group 12, (c) metal elements in group 13, (d) organic reducing agents, and (e) carbon monoxide. |
