- GAS PHASE REACTION OF CF3CN AND OTHER NITRILES WITH CHLORINE ATOMS
-
The photolytically induced reaction of Cl2 with some nitriles was investigated in the gas phase at room temperature.The reaction with CF3CN produced CF3CCl=NCl, CF3CCl=N-N=CClCF3 and CF3CCl3 as well as minor quantities of CF3(Cl)C=N-CCl2CF3, CF3CCl2(CF3)C=N-N=C(Cl)CF3, CF3CCl2-N=N-CCl2CF3, CF3CCl2(CF3)C=N-CCl2CF3 and CF3CCl2(CF3)C=N-N=C(CF3)CCl2CF3. ClCN reacted in a similar way giving CCl2=NCl, CCl2=N-N=CCl2 and CCl4 as principal products. On the other hand, when HCN was allowed to react with chlorine atoms, only ClCN, CCl2=NCl and CCl4 were obtained.No compounds containing C-H bonds were found. Possible reaction schemes taking into account the products obtained are discussed.

- The Preparation and Some Reactions of 2,5-Dichloro-1,1,1,6,6,6-hexafluoro-3,4-diazahexa-2,4-diene
-
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.
