Synthesis of 5,7-dichloro-2-adamantanone

Abstract

The reaction of 2-adamantanecarboxylic acid with an excess of chlorine in the presence of AlCl3 under heating gave 5,7-dichloro-2-adamantanecarboxylic acid. This product was sequentially introduced into the Curtius, deamination, and oxidation reactions to form 5,7-dichloro-2-adamantanone. The resulting product is a key substrate for synthesis of new substances and materials with a set of practically important properties, including both the synthesis of biologically active molecules and systems for chemiluminescent diagnostic methods.
