Abstract

PURPOSE: To prepare a dicyanoanthraquinone derivative useful as a synthetic intermediate of dyes, in high purity and yield, with simple operation, by cyanizing an anthraquinone derivative in the presence of a quaternary ammonium compound and a dehydrogenating agent.
CONSTITUTION: 1,4-Diamino-2,3-dicyanoanthraquinone is prepared by reacting 1,4- diamino-anthraquinone-2-sulfonic acid, its salt, or 1,4-diamino-2-cyanoanthraquinone with a cyanizing agent such as NaCN in an aqueous medium in the presence of a dehydrogenating agent such as nitrobenzenesulfonic acid and a quaternary ammonium compound such as tetramethylammonium chloride. The addition of the quaternary ammonium compound remarkably reduces the amount of by-rpoducts, and facilitates the purification operation. The quaternary ammonium compound can be recovered and reused after the reaction.
