Chemical infobox
Adamantane (tricyclo*decane) is a colourless, crystalline powder, that smells like camphor . It is a cycloalkane and also the simplest diamondoid, with a formula of C10H16. Adamantane is found in petroleum, where it was first isolated from in 1933, and some mountain crystals.

The first synthesis was done by Prelog in 1941. A more convenient method was found by Schleyer in 1957, using rearrangement reactions.

It melts at 270 °C and in atmospheric pressure sublimes before boiling. It is slightly soluble in water, and has a density of 1.07 g/cm³. Adamantane is very stable hence its name derived from adamant. It is used in polymers to give them special properties. It is also used in pharmacy, as eg. its derivates amantadine and rimantadine. It is also used in some dry etching masks.

In solid-state NMR spectroscopy, adamantane is a common standard for chemical shift referencing.

In dye lasers, adamantane may be used to stretch the life of the gain medium; it cannot be photoionized because it lacks ultraviolet absorption bands.

Adamantane derivatives


Adamantane derivatives with application in medicine are amantadine, memantine and rimantadine. Condensed adamantanes or diamondoids have been isolated from petroleum fractions, where they occur in small amounts. These species are of interest as molecular approximations of the cubic diamond framework, terminated with C-H bonds. 1,3-dehydroadamantane is a member of the propellane family.
