| Abstract: | The reaction of benzophenone arylhydrazones1 with bromine in pyridine solution yields 1-(arylazo-diphenylmethyl)-pyridinium bromides2 and pyridine · HBr. The inseparable salt mixtures upon treatment with a series of O- and N-nucleophiles undergo displacement of the pyridinium moiety of2 affording the title compounds3–14. |
