Partial Hydrogenation of Polycyclic Aromatic Hydrocarbons by Electroreduction in Protic Solvents

Polycyclic aromatic hydrocarbons (PAH) such as anthracene (1), phenanthrene (5), acenaphthylene (15), pyrene (17), chrysene (22), and fluoranthene (28) are selectively hydrogenated upon electroreduction at a lead cathode in ethanolic solution. The degree of hydrogenation and the structure of the products depend on the reaction conditions, in particular on the applied reduction potential.

Comparison of nickel boride and Raney nickel electrode activity in the electrocatalytic hydrogenation of phenanthrene

The electrocatalytic activity of nickel boride in the electrocatalytic hydrogenation of phenanthrene in ethylene glycol-water at 80°C has been compared to that of Raney nickel and fractal nickel. It is shown that the intrinsic activity of the electrode material (real electrode activity) is the same for nickel boride and Raney nickel electrodes and is lower for fractal nickel electrodes. The apparent electrode activity of nickel boride pressed powder electrodes is less than that of codeposited Raney nickel electrodes and pressed powder fractal nickel/Raney nickel electrodes. The relation in terms of the Tafel and alternating current impedance parameters are also determined.

Hydrogenation of Aromatic Hydrocarbons by Al/Ti Reagents

Treatment of anthracene (A) with LiAlH4 (LAH) at 150 deg C under atmospheric pressure gives 9,10-di- and 1,2,3,4-tetrahydroanthracene (2H-A and 4H-A).At 160-200 deg C and under hydrogen pressure (10-90 bar) a number of simple and polycyclic aromatic compounds are converted to fully or partially hydrogenated arenes.Addition of small amounts of TiCl4 or TiCl3 and the choice of solvents (heptane or glymes) have marked effects on the reaction.The pair triethylaluminium/TiCl4 acts also as efficient hydrogenation catalyst.
