Process for preparation of dihalogenoadamantanes |
| abstract |
This invention discloses a process for preparing a dihalogenated adamantane by reacting an adamantane optionally substituted with alkyl at 1-position with a halosulfonic acid, comprising the first stage of monohalogenation conducted at −5 to 15° C. and then the second stage of dihalogenation conducted at 17 to 35° C., preferably in the absence of an organic solvent. |
