  7. Abstract:
  8. Dithiocarbamate is one of the most useful components in the science of chemistry. They are used not only in agriculture as fungicides but also in photochemistry in order to determine and analyse NO in biological processes as well as in polymerization routes. Dithiocarbamates which are known as bidentate ligands with high yield are applied in many fields such as producing chemical drugs, functioning as intermediates in organic synthesis, protecting groups in peptide synthesis as well as highly chelating ligands. Regarding the high practically of dithiocarbamates and by focusing on their synthesis process, we have applied them as bidentate ligands. Cinnamaldehyde was condensed in ethanol with diamines (1,3-Diaminopropane, 1,4-Diaminobutane, 1,6-Diaminohexane) to form the imines. Sodium borohydride reduction of the imines in methanol afforded the related amine as yellow oil. The final complexes were prepared via in situ reacyion of the amines, CS2 and related metal salts. Three amines utilized in this study and nineteen different complexes were prepared. All final products were filtered and recrystallized with chloroform and n-hexane. The ultimate product was studied with IR and NMR. Finally, the ultimate complexes were analyzed by CHN, IR and TGA.
