    摘要: This invention provides a method for deuterating a haloacrylic acid or its salt with high efficiency on a commercial scale. The method is characterized in that a compound represented by general formula [1] wherein R1 and R2 each independently represent a light hydrogen atom or a heavy hydrogen atom, and at least one of R1 and R2 represents a light hydrogen atom; R3 represents a light hydrogen atom, a heavy hydrogen atom, an alkali metal atom, or an alkaline earth metal atom; X represents a halogen atom; and n represents 1 or 2, is reacted with a heavy hydrogen source in the co-presence of a catalyst selected from palladium catalysts, platinum catalysts, rhodium catalysts, ruthenium catalysts, nickel catalysts, and cobalt catalysts not subjected to activation treatment. The deuterated compound is represented by general formula [2] wherein R4 and R5 each independently represent a light hydrogen atom or a heavy hydrogen atom, and at least one of R4 and R5 represents a heavy hydrogen atom; R3 represents a light hydrogen atom, a heavy hydrogen atom, an alkali metal atom, or an alkaline earth metal atom; X represents a halogen atom; and n represents 1 or 2.
