METHOD OF OBTAINING 1-HYDROXYADAMANTAN-4-ONE (KEMANTANE) Russian patent published in 2014 - IPC C07C49/513 C07C29/09

Abstract RU 2507191 C1

FIELD: chemistry.

SUBSTANCE: invention relates to method of obtaining 1-hydroxyadamantan-4-one from adamantanone-2. Adamantanone-2 is brominated by means of CBrCl₃ under action of catalyst Mo(CO)₆, activated with pyridine with molar ratio [Mo]:[Py]:[AdO]:[CBrCl₃]=1-10:200-1000:1000:1000-2500, at temperature 175°C for 6-20 hours with further hydrolysis of formed 1-bromadamantan-4-one.

EFFECT: method makes it possible to carry out the process in absence of aggressive reagents of halogenation and use bromating agent in equimolar amount with respect to adamantanone.
