Lithium acetylide was reacted with adamantanone, verbanone, and verbenone t
o obtain their hydroxyethynyl derivatives whose reaction with aqueous ammon
ia solution of silver nitrate gave the corresponding polycycloaliphatic sil
ver acetylides. The latter react with iodine, yielding hydroxyethynyl iodid
es. Acetates of the adamantane-containing ethynyl alcohols were prepared.
