Diamonds are a Chemist's Best Friend: Diamondoid Chemistry Beyond Adamantane

“…(9)]. [63] An even better synthesis for 3 was discovered by Hamilton et al when heating 13 on a platinum catalyst in the absence of hydrogen gas, [64,65] which results in the formation of cyclic monoolefins that undergo Diels-Alder reactions with butadiene. Hydrogenation/Lewis acid rearrangement gave 3 with moderate yield [Eq.…”

“…By changing the diene from butadiene to isoprene it was possible to isolate various methyl derivatives of 3. [65] This kind of reaction pathway was studied in more detail by Kafka et al by using various Lewis acids for the isomerization of 13; [66,67] the products of the Diels-Alder reaction with the resulting hexacyclic olefins were also studied. [68] Farooq et al showed that it is also possible to catalyze the rearrangement of heptacyclooctadecanes with superacids and to get a 70 % yield of 3 [Eq.…”

Atmospheric pressure synthesis of diamondoids by plasmas generated inside a microfluidic reactor

“…To date, the only higher diamondoids realized by organic synthesis are triamantane [18] and anti-tetramantane [19]. The main cause is that with increasing cage number, the amount of potential reaction steps and intermediates mounts exponentially [20].…”
