9-アミノフェナントレンとその誘導体の合成

抄録

Synthesis of 9-aminophenanthrene (3) from 9-bromophenanthrene (2) and aqueous ammonia in the presence of copper-catalyst has been investigated. By using copper sulfate as a catalyst in an autoclave at 200°C yielded 65% of (3) from (2). On the other hand, the use of cuprous oxide was effective to proceed the reaction at lower temperature but this yielded a large amount of phenanthrene as a by-prod-uct and decreased the yield of (3). Aromatic diazo compounds were coupled with (3) to yield aminoazo compounds and these were oxidized with chromic anhydride in pyridine to yield triazole compounds.
