摘要:
Triflic acid catalyzed reaction of 2-hydroxy-2-adamantanecarboxylic acid results via ionizative decarbonylation in the formation of adamantonone. Under carbon monoxide pressure pinacol-type rearrangement gives 4,5-homoadamantanedione. Reaction of a series of alpha-hydroxy ketones result in fragmentation, deprotonation, and cyclization, respectively. The reactions and their suggested mechanism are discussed.
