    摘要: The present invention relates to a hydrodehalogenation method in which a halogen atom on a carbon atom of an organic compound is removed by substituting the halogen atom with a hydrogen atom, and to a method for producing a dehalogenated compound. The hydrodehalogenation method is characterized by including treating an organic compound having a halogen atom on a carbon atom thereof in a solvent with a compound represented by formula (2-1):

            M 2 BH p R 1 q      (2-1)

    or formula (2-2) :

            M 3 (BH p R 1 q ) 2      (2-2)

    (wherein M 2 represents an alkali metal atom; M 3 represents an alkaline earth metal atom or a zinc atom; R 1 represents a hydrogen atom, a cyano group, a C2-C13 acyloxy group, or a C1-C6 alkoxy group; p is an integer of 1 to 4; q is an integer of 0 to 3; and the sum of p and q is 4) in the presence of a Group VIII metal complex represented by formula (1):

            M 1 X m L n      (1)

    (wherein M 1 represents a Group VIII metal; X represents a halogen atom; L represents a neutral ligand; m is an integer of 1 or 2; n is an integer of 2 or 3; and the sum of m and n is 4).
