[Octakis(3,5-bis-trifluoromethyl-benzylthio)porphyrazinato] magnesium carrying eight (3,5-bis-trifluoromethyl-benzylthio) groups on the peripheral positions have been synthesized by cyclotetramerization of 1,2-bis(3,5-bis-trifluoromethyl-benzylthio)maleonitrile in the presence of magnesium butanolate. Its demetalation by the treatment with trifluoroacetic acid resulted in the metal-free derivative. Further reaction of this product with copper(II) acetate, zinc(II) acetate and cobalt(II) acetate have led to the metallo derivatives M = Cu(II), Zn(II), Co(II). These novel complexes were characterized by elemental analysis, together with FT-IR, 1H NMR, 13C NMR, 19F NMR, UV–vis and mass spectral data.
