Reactions of halogenomethanes in the vapour phase. Part 5. The reactions of imidazolines, anils, and 1-methylimidazole with chloroform at 550 °C, and a comparison with their liquid-phase reactions with trichloroacetate ion or hexachloroacetone and base

Abstract

The vapour-phase reactions of Imidazolines and anils with chloroform at 550 °C are compared with their liquidphase reactions in the presence of hexachloroacetone and base or upon thermolysis with trichloroacetate ion. In the vapour-phase reactions Imidazolines, unlike imidazoles, gave non-chlorinated pyrimidines, and 1-methylimidazole gave 2-cyanopyrrole and the four 3-chlorocyanopyridines.
