Anhydrides and phenylimides of 4-(5-aryl-2-oxazolyl)naphthalic acids

A number of 4-(5-aryl-2-oxazolyl)naphthalic anhydrides were obtained by condensation of 4-chloroformylnaphthalic anhydride with -aminomethyl aryl ketones and subsequent cyclization of the resulting amides; N-phenylimides were obtained from the anhydrides by reaction with aniline. The relationship between the structures of the substances obtained and their UV and luminescence spectra was investigated.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 10, pp. 1331–1333, October, 1973.
