Trifonov, R. E. published the artcileBasicity of phenyl-substituted 1,3-oxazoles, Category: oxazolidine, the publication is Russian Journal of Organic Chemistry (Translation of Zhurnal Organicheskoi Khimii) (2001), 37(3), 416-420, database is CAplus.
Ph substituents in positions 2, 4, and 5 of the oxazole ring exert different effects on the electronic structure of the hetero ring, which are reflected in the basicity constants of isomeric phenyl-substituted oxazoles and in changes of the spectral patterns on protonation. The calculated (AM1) gas-phase proton affinities and energies of ionization of isomeric methyl-, phenyl-, and methylphenyloxazoles were correlated with the exptl. pKBH+ values. In acid medium specific solvation of phenyloxazoles is possible with participation of the heterocyclic fragment.
