Synthesis of New Polyamine Ligands Using Vinamidinium Salts

In the present study, synthesis of new polyamine ligands using vinamidinium salts in the presence of N-ethyl diisopropylamine in ethanol were reported. In the first part of this study, the synthesis of new polyamine ligands has been reported, in the presence of N-ethyl diisopropylamine in ethanol in three steps: 1. Preparation of N-heteroaryl acetic acid salts, 2. Synthesis of vinamidinium salts and 3. synthesis of polyamine ligands using vinamidinium salts. In the second part, from the reaction of nickel acetate with synthesized polyamine compounds in DMSO as the solvent, the corresponding nickel (II) complexes were obtained and studied by UV spectroscopy.
