Spectroscopic study of selenadiazoloquinolones in alkaline media
Abstract
Newly synthesized derivatives of 6–oxo–6,9–dihydro[1,2,5]selenadiazolo [3,4–h] quinoline variously substituted at position 7are witnessed in solution in the N9–deprotonated and protonated oxo tautomeric forms depending on the pH using UV/vis and NMRspectroscopy. Upon the anodic oxidation selenadiazoloquinolonesproduce paramagnetic species observed by EPR spectroscopy.
