Adamantane was discovered in petroleum in 1933.4 Its name derived from the Greek adamantinos relating to steel or diamond, due to its diamond-like structure.5 Adamantane is the most stable isomer of C10H16. Contents 1 Synthesis 2 Uses 3 Adamantane derivatives 4 Adamantane analogues 5 References Synthesis Adamantane was first synthesised by Prelog in 1941.67 A more convenient method was found by Schleyer in 1957, from dicyclopentadiene by hydrogenation followed by acid-catalysed skeletal rearrangement.89 Uses Adamantane itself enjoys few applications since it is merely an unfunctionalised hydrocarbon. It is used in some dry etching masks.10 It is also used in some polymer formulations. In solid-state NMR spectroscopy, adamantane is a common standard for chemical shift referencing.11 In dye lasers, adamantane may be used to extend the life of the gain medium; it cannot be photoionised under atmosphere because its absorption bands lie in the vacuum-ultraviolet region of the spectrum. Photoionization energies have been determined recently for adamantane as well as for several bigger diamondoids.12 Adamantane derivatives Adamantane derivatives are useful in medicine, e.g. 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. Due to its stability, specific steric properties and conformational rigidity, the 1-adamantyl group is a bulky substituent in organic and organometallic chemistry. Some of the first persistent carbenes featured adamantyl substituents. Adamantane analogues Many molecules adopt cage structures with adamantanoid structures. Particularly useful compounds with this motif include P4O6, As4O6, P4O10 = PO4O6, P4S10 = PS4S6, and N4CH26.13 References ^ According to page 41 of a 2004 IUPAC guide, adamantane is the preferred IUPAC name. ^ SID 152429 -- PubChem Substance Summary.
