Abstract:

Ring closure of the N perfluoroacylimidoyl perfluoroalkyl amidine by acylation with perfluoroacyl chloride was apparently hindered by formation of a hydrochloride salt of the acylated product formation and acylation of the silver salt of the imidoyl amidine yielded the desired triazine quantitatively. The reaction of perfluoroadiphydrazidine with perfluoroadiponitrile produced the intermediate polyimidoylhydrazidine as a step in a perfluoroalkyltriazole polymer synthesis. Reaction of perfluoroglutaronitrile with N2H4 produced a cyclic compound which may be useful as a single monomer for formation of the intermediate polymer. The 5-perfluoroalkyl tetrazoles were useful intermediates for the synthesis of the perfluoroalkyl substituted 1,2,4-triazoles and pyrazoles. From pyrolysis of the tetrazoles, 3,6-aisperfluoroalkyl1,2-dihydro-1,2,4,5-tetrazine was isolated, and perfluorobutyrnitrilimine was separated and identified. Author
