ABSTRACT:
1,2,3-Tricyanobenzene can be prepared in a good yield from fluorobenzonitriles by reaction with an alkali metal cyanide. This product can be converted into metal-free tetracyanophthalocyanines or into the corresponding metal complexes by tetramerisation, if appropriate in the presence of metals or metal compounds. These products are excellent organic pigments.
