A Convenient Procedure for the Preparation of Adamantanone

Abstract

Sinoe adamantanone is a useful and versatile startin material for secondary substituted and ring-transformed adamantanes¹we wish to report on a convenient synthesis of this ketone from adamantans with 98 percent sulfuric acid. Adamantanone may be prepared in basionally the same way, starting from 1-adamantanol, which gives abtter yield and needs a shorter reaction tine²but adamantane affords a more direot routs. The producer reported here is based on a 100-g scale, but this scale may be extended to 1 kg.
