Abstract
The present invention provides a process for preparing an adamantane polyol by reacting an adamantane with a ruthenium compound and a hypochlorite in a biphasic water/organic solvent system. The process includes the steps of adding an inorganic adsorbent to a reaction system; and adding an alkali to a reaction mixture to separate the ruthenium compound together with the inorganic adsorbent, and reusing the separated ruthenium compound and inorganic adsorbent in a subsequent reaction.
