Polarographic study of halogen and mercury substituted 1,3-oxazoles

A study is made of the polarographic behavior of some halogen and mercury derivatives of phenyloxazoles. By considering the mechanism of electroreduction, it is ascertained, that, the first polarographic wave corresponds to reduction of the halogen or mercury-containing substituent, and the second to reduction of the heterocyclic ring. By analysis of polarographic data it is shown that the electron density sequence for carbon atoms in the oxazole ring is C-2<C-5<C-4.
