Abstract: Provided is a method for purifying a phosphorus-containing olefin compound salt as a raw material or an intermediate that is useful to increase the purity of a target product in a method for producing an olefin compound and that can be applied to the production method, and a method for producing an olefin compound using a purified product obtained thereby.
Specifically, provided is a method for purifying a phosphorus-containing olefin compound salt, comprising reprecipitating and/or recrystallizing a solid comprising at least one phosphorus-containing olefin compound salt selected from the group consisting of: a phosphorus-containing olefin compound salt A represented by the following formula (1): wherein X1 and X2 are each independently F, Cl, Br, I, or H; W+s are the same or different and each is a monovalent cation comprising PR3 or P(OR)3, provided that Rs are groups having a saturated or unsaturated structure containing C and H, are optionally bonded together to form a ring, and optionally contain an atom other than C and H; three Rs included in R3 and (OR)3 are optionally the same or different; and M− is a monovalent anion comprising an atom or a compound; and a phosphorus-containing olefin compound salt B represented by the following formula (2): wherein X1, X2, W+, and M− are as defined above, and Y is F, Cl, Br, I, H, an alkyl group, an alkyl ether group, a fluoroalkyl group, or a fluoroalkyl ether group; in a solvent, thereby obtaining a purified product of the phosphorus-containing olefin compound salt.
