Abstract

Abstract A series of previously unknown unsymmetrical difluoroaromatic compounds, viz., p- fluorobenzoylphenyl (p-fluorophenyl)-substituted imidazoles, pyrazines, and quinoxalines, were synthesized according to multistep procedures with the use of chloral as the key compound. The reactivities of the resulting difluoroaromatic compounds were estimated based on 19 F and 13 C NMR spectral data and the results of quantum-chemical ...
