To provide a method for producing 4,9-dibromodiamantane selectively and in a good yield.
This method for producing the 4,9-dibromodiamantane selectively by reacting bromine with diamantane in the presence of a lewis acid is characterized by using a 3-10C substituted or non-substituted linear, branched or cyclic saturated hydrocarbon-based solvent, and satisfying the relationship of formula (1): A/(A+B+C+D+E)0.80 [wherein, A is the areal ratio(%) of 4,9-dibromodiamantane obtained by the gas chromatographic measurement of solution after completing the reaction; B is the areal ratio of diamantane; C is the sum of the areal ratios of 1-bromodiamantane and 4-bromodiamantane; D is the areal ratio of tribromodiamantane; and E is the sum of the areal ratios of 1,6-dibromodiamantane and 1,4-dibromodiamantane].
