Synthesis of new tetrathiafulvalenes with aromatic substituents and related metallic dithiolene complexes

Synthesis of square-planar complexes and the corresponding TTFʹs derivatives with 4-(substituted)1,2-dithiolene as ligands can be achieved starting from the corresponding thione or ketone in an ethoxide solution. Complexes of Ni(II) and Au(III) have been prepared using 4-(p-Cyanophenyl) and 4-(4-pyridil)1,3-dithiole-2-thione as precursors.
