“…Oxazolones (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15) were prepared according to recommended procedure (13). The purity and structures of the compounds were checked by measurements of mp, nmr, mass spectra, and elemental analysis.…”

“…On the other hand, the polarographic behaviour of the oxazole ring, structurally a heterocyclic system, has attracted only minor attention in literature (3, 4) as compared to major spectroscopic investigations (5)(6)(7)(8)(9)(10). Consequently, in the present investigation our attention was devoted mainly to oxazolones possessing wide applications in the electrosyntheses of various amino alcohols, thiamine, and amino acids (11,12).…”

“…Consequently, in the present investigation our attention was devoted mainly to oxazolones possessing wide applications in the electrosyntheses of various amino alcohols, thiamine, and amino acids (11,12). The study was focussed on the polarographic behaviour of some oxazolones (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15), in Thiel buffer -ethanolic solutions of different pH values as well as in DMF. The electrode reaction mechanism and various physical properties of these compounds were also investigated.…”

M. I. ISMAIL. Can. J. Chem. 69, 1886 (1991.The redox potential (AEI12), electron affinity (EA), ionization potential (IP), coulomb repulsion integral (J12). and electronic transition energy (ECT) of several oxazolone derivatives in DMF were computed. A linear correlation was shown to exist between and ECT The polarographic reduction was investigated in ethanolic-Theil buffer solutions. At pH < 7.2, two waves were obtained representing the uptake of 2-and 4-electron steps respectively. In alkaline media, a third wave appeared seemingly a result of the hydrolysis of oxazolones. The rate of hydrolysis was determined and the electrode mechanism was elucidated and confirmed via spectrophotometric and coulometric analysis.
