Acenaphthene and fluorene hydrogenation on industrial aluminum oxide catalysts in a flow system

Hydrogenation of the tricyclic aromatic hydrocarbons acenaphthene and fluorene on industrial aluminum oxide catalysts in a flow system has been studied. It has been found that total these hydrocarbons are exhaustively hydrogenated in the presence of a nickel-chromium catalyst at 200°C and a pressure of 100 atm to give isomer mixtures of the corresponding perhydroaromatic hydrocarbons decahydroacenaphthene and dodecahydrofluorene. The liquid products obtained can be of interest as components of hydrocarbon fuels with increased density. Certain conformational features of the stereoisomers obtained have been considered. It has been assumed that some spatial isomers of decahydroacenaphthene have six-membered rings in the boat conformation.

Synthesis of Stereoisomeric Ufolanes

Three of the six possible stereoisomers of dodecahydroacenaphthylene, t,t,t-ufolane (1), c,c,t-ufolane (3), and c,c,c-ufolane (5), have been synthesized for the first time.The configurations have been confirmed inter alia by an X-ray analysis of the precursors 11, 14, and 23 and the bromine adduct 24 of c,c,c-10-ufolene (19), the precursor of 5.
