Method for producing alkenyl phosphorus compound

Abstract

Provided is a method for producing an alkenyl phosphorus compound which can produce an alkenyl phosphorus compound efficiently even with a smaller amount of a catalyst used than that used conventionally, and further which can maintain catalytic activity to produce an alkenyl phosphorus compound in high yield even at a larger reaction scale, and which can also be applied to quantity synthesis at an industrial scale using a conventional batch reactor or continuous reactor. A method for producing an alkenyl phosphorus compound, comprising: a step of reacting a compound represented by the following formula (1): [In formula (1), Rrepresents ORor R, Rrepresents ORor R, and Rand Rrepresent, for example, each independently a substituted or unsubstituted alkyl group.] with a compound represented by the following formula (2): [In formula (2), Rrepresents, for example, a hydrogen atom, or a substituted or unsubstituted alkyl group.] to produce the phosphorus alkenyl compound presented by at least any of the following formulas (3) or (3): [In formulas (3) and (3), Rand Rhave the same meaning as defined in formula (1), and Rhas the same meaning as defined in formula (2).], In which the compound represented by formula (1) is reacted with the compound represented by formula (2) using a transition metal catalyst, and a phosphorus oxo acid compound having an intramolecular P—H bond.
