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.

Synthesis of 9-Methylene-9,10-dihydroanthracene by Lithium Aluminium Hydride Reduction of (9-Anthrylmethyl)trimethylammonium Chloride

Treatment of (9-anthrylmethyl)trimethylammonium chloride (2a) with 1 mol equiv. of lithium aluminium hydride (LAH) in refluxing tetrahydrofuran gave predominantly 9-methylene-9,10-dihydroanthracene (3a).However, reaction with 3 mol equiv. of LAH gave a mixture of 9-methyl-9,10-dihydroantracene (5a) and 9-(9-anthrylmethyl)-9-methyl-9,10-dihydroanthracene (6a), these products being formed by processes involving nucleophilic attack of excess of LAH on compound (3a).
