Photochemical Behaviour of 9-(2-Anilinoethyl)- and 9-(3-Anilinopropyl)anthracenes in Various Solvents

Photochemical reactions of the title compounds and related aniline derivatives have been studied in various solvents.Products isolated from an irradiated mixture of 9-(2-anilinoethyl)anthracene (5) were: 9-methylene-9,10-dihydroanthracene (6), N-phenyl-9,

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).
