    • A process for selectively producing 4,9-dibromodiamantane includes a step of reacting diamantane with bromine in the presence of a Lewis acid and a solvent, wherein the solvent comprises a substituted or unsubstituted, straight-chain, branched-chain or cyclic saturated hydrocarbon containing from 3 to 10 carbon atoms, and a reaction solution after the step satisfies Formula (1): A/(A+B+C+D+E) > 0.80 Formula (1) wherein A represents an area ratio (%) of 4,9-dibromodiamantane obtained by gas chromatography of the reaction solution, B represents an area ratio of diamantane, C represents a sum of an area ratio of 1-bromodiamantane and an area ratio of 4-bromodiamantane, D represents an area ratio of tribromodiamantane, and E represents a sum of an area ratio of 1,6-dibromodiamantane and an area ratio of 1,4-dibromodiamantane.
