Abstract:
1. A process for selectively producing 4,9-dibromodiamantane, comprising: 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 saturated hydrocarbon containing from 3 to 10 carbon atoms, a substituted or unsubstituted branched-chain saturated hydrocarbon containing from 3 to 10 carbon atoms, or a substituted or unsubstituted cyclic saturated hydrocarbon containing from 3 to 10 carbon atoms, and a reaction solution after the step satisfies 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.
