The title azine(I) can be conveniently prepared by treatment of 1,2-bistrifluoroacetylhydrazine with NN-dimethylaniline hydrochloride in phosphoryl chloride at ca. 100 deg C.It undergoes facile displacement of one or both chlorine atoms on treatment with a variety of nitrogen-, oxygen- and sulphur-centred nucleophiles as well as with iodide and fluoride ions.The bisanilino-substituted azine (Vd) is thermally unstable and cyclises with elimination of aniline to the triazole (VIa), while the perfluoroazine (Vj) undergoes cycloaddition with acetylene.
