Japanese Patent JPH0242817
Kind Code:
B2
Abstract:
A new widely-applicable method has been found for synthesis of 9,10-anthraquinones and similar chemical compounds of wide use in industry and pharmacology, by reacting suitable aromatic substrates with activated dicarboxylic acids (more particularly dichlorides) in the presence of metal halides. The special characteristics of the reaction are the good yields, high selectivity, the possibility of operating in a single reactor and the use of starting compounds which are cheap and easily available on the market.
