Isolierung von Tetracyclo[6.3.1.02, 6.05, 10]dodecan und Pentacyclo[7.3.1.14, 12.02, 7.06, 11]tetradecan (Diamantan) aus Erdöl

Abstract: rotierenden Kugelrohr auf 130 "C, so spaltet sich Triphenylphosphinoxid ab, und es destilliert quantitativ das Azirin (4) Cber, das im IR-Spektrum eine charakteristische Bande bei 5,7p und im UV-Spektrum eine Absorption bei 246mp reigt (Kernresonanz: Singulett fur die Methylprotonen be1 T = 8,51, Multiplett fur die aromatischen Protonen bei T ~ 2,3). (4) wird in methanolischer Salzsaure zum Aminoketonhydrochlorid (5) verseift (Pikrat, Fp = 174 "C, Lit. 121 175 "C). /CH3@NH, ci0DaCNitriloxid ( I ) reagiert in B… Show more

“…Lower diamondoids involve diamantane (1, synthesized [2] and isolated from petroleum [27] in the 1960s); triamantane (2) [4] and C 2h -tetramantane (anti-tetramantane, 4), [5] which were prepared synthetically and were also isolated from petroleum recently. C 2 -Tetramantane (skew tetramantane, 3), C 3v -tetramantane (isotetramantane, 5), T d -pentamantane (6), [12] and D 3d -hexamantane (cyclohexamantane, 7) [13] are currently only available from petroleum.…”

“…Adamantane [17] (1) and Diamantane [18] (2) were both discovered from the same crude oil near Hodonin, Czechoslovakia in 1933 and 1966, respectively. Since no methods for isolating and purifying 1 and 2 were developed, studying diamondoids from oil was not considered further for a long time.…”

“…Im Jahr 1966 gelang es Wissenschaftlern der gleichen Universität (Stanislav Landa, Slavoj Hala, und Vladimir Hanus), auch Diamantan aus derselben Petroleumquelle zu isolieren [7]. Im gleichen Jahr war Adamantan auch das Thema einer tschechoslowakischen Briefmarke zu Ehren des hundertjährigen Bestehens der Tschechischen Chemischen Gesellschaft (Abbildung 7).…”
