Coumarin phthalonitriles: Synthesis and cation binding properties
Journal Title: JOURNAL OF ADVANCES IN CHEMISTRY - Year 2015, Vol 11, Issue 4
Abstract
Coumarin possess a number of biological activities like anticoagulant, antimicrobial, anti-inflammatory, analgesic,antioxidant, anticancer, antiviral, antimalarial etc. Coumarin belongs to a group as benzopyrones, which consists of a benzene ring joined to a pyrone nucleus. In this work, new coumarin phtalonitriles derivatives were synthesized and characterized via spectroscopic techniques IR, 1H NMR, 13C NMR, mass spectra and elemental analysis.The synthesis of coumarin phtalonitriles resulting from a nucleophilic aromatic substitution reaction between 4-nitrophtalonitrile and coumarins derivatives. The complexing properties of the coumarin derivatives toward alkali metal, alkaline earth metal, some transition metals and some heavy metal cations have been investigated in acetonitrile by means of UV spectrophotometry absorption and conductivity methods. Thus, the stoichiometry of the complexes formed and their stability constants were determined
