Extracomplexes of metals of groups III and IV of the periodic system with tetrasubstitued phthalocyanines containing halogen atoms, nitro-, amino-, hydroxy-, cyano-, and tert -butyl groups as substituents were synthesized. Their spectral and other properties were characterized.
Provided are methods for preparing a phthalocyanine pigment in high yield that eliminate the need to add a heavy metal catalyst. The resulting pigmentary phthalocyanine products thus contain no or only trace amounts of heavy metal impurities. The provided methods produce phthalocyanine pigments that can be used in any application that utilizes phthalocyanine pigments, such as in dispersions, printing inks, paints, plastics and coatings.

is fluorine and to a process for preparing them.
Compounds such as pentafluorobenzonitrile, tetra- fluorophthalonitriles, and pentafluoropyridine are produced by halogen exchange with a chloro- or bromo-organic compound fluorinating agent such as an alkali metal fluoride using benzonitrile as a solvent as from 190° to 400°C.
