The syntheses of various bromo and iodo derivatives of copper phthalocyanine pigments are reported; the halogenated primaries always led to trimeric or tetrameric acyclic compounds. Copper atoms were incorporated into the structures obtained from the corresponding iodinated primaries. An indirect route to the synthesis of copper tetra-3-iodophthalocyanine via the syntheses of copper tetra-3-amino- and copper tetra-3-nitro-phthalocyanine pigments is also reported.
