Title:
METHOD FOR PRODUCING DIHALOGENATED ADAMANTANES
Document Type and Number:
Japanese Patent JP2005075808
Kind Code:
A
Abstract:

To provide a method for producing dihalogenated adamantanes, capable of surely preventing a reaction from a violent progression caused by a sudden progress of the reaction in producing the dihalogenated adamantanes in performing the reaction of the adamantanes with 5-15 equivalents halosulfonic acid, and also exhibiting a higher yield than those in the case of using a metal or metal oxide.

This method for producing the dihalogenated adamantanes is provided by adjusting reaction temperature and adding amount of the halosulfonic acid so that a state of adding the halosulfonic acid of ≥2 and ≤4 equivalents and keeping temperature at ≥17°C, is maintained for at least 2 hr in the reaction system.
