只要摘要，在sciendirect數(shù)據(jù)庫中 The preparation and some reactions of 2,5-dichloro-1,1,1,6,6,6-hexafluoro-3,4-diazahexa-2,4-diene Michael G. Barlow, David Bell, Neil J. O'Reilly and Anthony E. Tipping Department of Chemistry, University of Manchester Institute of Science and Technology, Manchester M60 1QD U.K. Received 29 April 1983; accepted 24 May 1983. Available online 5 March 2001. Abstract The title azine(I) can be conveniently prepared by treatment of 1,2-bistrifluoroacetylhydrazine with - dimethylaniline hydrochloride in phosphoryl chloride at . 100 °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 (Vla), while the perfluoroazine (Vj) undergoes cycloaddition with acetylene. https://www.sciencedirect.com/sc ... i/S0022113900851349 |
