, p. 456 - 463 (2018/12/11)
Refluxing of 1,3-oxazolone (1a) with malononitrile in dry benzene and in the presence of ammonium acetate afforded imidazolone derivative (2). However, carrying out the same reaction in absolute ethanol and in the presence of piperidine as a base gave the
Physical characteristics and polarographic reduction mechanism of some oxazolones
Ismail, M. I.
, p. 1886 - 1892 (2007/10/02)
The redox potential (ΔE1/2), 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 ΔE1/2 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. Key words: oxazolones, polarography, electrochemistry, electrode reaction, spectrophotometry, redox potential.
