Solvent-free conversion of linalool to methylcyclopentadiene dimers: A route to renewable high-density fuels

Neat biofuel in HD: Linalool, a linear terpene alcohol, can be selectively converted by ruthenium metathesis catalysts under solvent-free conditions to 1-methyl-cyclopent-2-enol and isobutylene in quantitative yield. Dehydration of the alcohol under mild conditions followed by low-temperature thermal dimerization yields methylcyclopentadiene dimer, which can be readily converted into a high-density fuel.

Zur Aromatisierung von n-Heptan an Pt-Sn/Al2O3- und Pt-Ir/Al2O3-Katalysatoren

The aromatization of n-heptane and methylcyclopentane has been investigated under normal pressure over catalysis with very different metal and acid functions.Under these conditions, Pt-Sn/Al2O3 is characterized by high activity and outstanding selectivities for dehydrogenation and dehydrocyclization via 1,6 ring closure.

66. The Hydrolysis of Ethyl 1-Methyl-2,4-cyclopentadiene-1-carboxylate by Nonenzymatic and Enzymatic Methods. Carbon-Carbon vs. Carbon-Oxygen Bond Cleavage

The title ester 5 is shown to undergo C-C bond cleavage under the conditions of basic ester hydrolysis (KOH/EtOH) with formation of potassium ethyl carbonate (6) and the tautomeric methylcyclopentadienes 7 and 8.In contrast, porcine liver esterase (PLE, EC 3.1.1.1) cleanly hydrolyses 5 to give the isolable 1-methyl-2,4-cyclopentadiene-1-carboxylic acid (13).The latter undergoes thermal dimerization with conservation of the geminal-substitution pattern.The configuration of the Diels-Alder adduct 17 is ascertained by it photochemical transformation into bishomocubane dicarboxylic acid 12, easily distinguished by its C2 symmetry.Under the conditions of acid-catalyzed hydrolysis, dimerization of ester 5 and polymerization prevail, unless low acidic concentration is used.The dimer 9 of 5 has one ester function that is reluctant to undergo basic hydrolysis.
