FEATURES OF THE OXIDATIVE POLYMERIZATION OF AMINOTHIAZOLE IN THE PRESENCE OF IRON(III) CHLORIDE

A new conjugated polymer with semiconducting characteristics – polyaminothiazole – was obtained by oxidative polymerization of 2-aminothiazole in the presence of iron(III) chloride. A reaction scheme is proposed on the basis of the data from IR, ESR, and electronic spectroscopy. It involves the formation of an intermediate aminothiazole–FeCl3 complex with coordination of the initiator at the nitrogen atom and subsequent oxidation of another molecule of aminothiazole by this complex with the formation of a radical-cation, leading to polymerization.
