Synthesis and spectral-lumine scence properties of 2- aryl- 4- benzylide ne-5-oxazolones
A number of 2-aryl-4-benzylidene-5-oxazolones was obtained by condensation of benzaldehyde with N-acylglycines. The absorption and fluorescence spectra in chloroform at 77 °K were measured. The spectral characteristics of the investigated and previously synthesized 2-phenyl-4-arylidene-5-oxazolones are compared.
