STUDIES ON METAL COMPLEXES OF SOME HETEROCYCLIC COMPOUNDS AND THEIR APPLICATION

This thesis deals with the synthesis of the ligands 6-amino-2-thiouracil and three of its derivatives and their complexes formed with copper, beside the uses of the ligands as antifouling and anticorrosive paint formulations . It comprises four chapters. Chapter two reviews the organic compounds used for fouling control such as azole, mercaptans, carbamate, pyrimidine and pyridine compounds. Besides, it deals with the biological activities, complexes and applications of thiouracil compounds.Chapter three includes the procedure used for the synthesis of 6- amino -2- thiouracil and three of its derivatives, description of the paint preparation containing the synthesized compounds and their testing. Also, it contains the methods of analysis andThe last chapter includes the results and their discussion in twelve parts. The first part describes the stoichiometry of the ligands : physical properties and proposed structures . The second part shows the mass spectra of the ligands and the electron im
