Diphenylthallium(III) thiosemicarbazonates: flexibility of coordination in the solid state and polymorphism in chloroform solution

Novel Nonmetalated Hydrophobic and Metalated Phthalocyanines Bearing Pyridine-2-Thiol and 2,4,6-Trimethylphenylamine Substituents: Synthesis, Spectroscopic, Aggregation and Thermal Properties

Novel metal–free and metallo-phthalocyanines, with different substituents at peripheral positions, have been synthesised by cyclotetramerisation of 4-(2,4,6-trimethylphenylamino)phthalonitrile and 4-(pyridine-2-ylsulfanyl)phthalonitrile in the presence of the corresponding divalent metal salts [Zn(II), Cu(II), Co(II) and Ni(II)]. Quaternisation of the metallophthalocyanine functionality produced quaternised cationic Zn, Cu, Ni and Co phthalocyanines, which are soluble in DMF, H2O and DMSO. The aggregation behaviour of these compounds was investigated in different concentrations of DMSO. Their thermal stability and electronic stability are reported.

What Can Be Done with the Acetyl Group of Aryl-1-Ethanones?

Literature data on utilization of acetyl group of aryl-1-ethanones (acetophenones) for the synthesis of organic compounds is generalized. Different approaches of preparation of aromatic compounds by chemical transformations of methyl as well as keto- group of titled compounds are systematized. Examples of the synthesis of organic compounds based on products of primary transformations of aryl-1-ethanones are considered.
