Zn(II), Co(II), Ni(II) and metal-free phthalocyanines (2-5) beating a hydroxyethylthio substituent on each benzo group were prepared from 4-(hydroxyethylthio)phthalonitrile (1) and the corresponding divalent metal salt. The reactivity of the hydroxyethyl groups was demonstrated by esterification of phthalocyanine, derivatives (2-5) with acetic anhydride at reflux temperature and acetylated phthalocyanine compounds (6-9) were obtained. The new compounds have been characterized by elemental analyses, IR, UV-vis, mass and H-1 NMR spectroscopy. (c) 2006 Elsevier Ltd. All rights reserved.
