Ev. Kabakchi et al., REACTION OF PERFLUORINATED NITRILES WITH BENZAMIDOXIMES AND TEREPHTHALAMIDOXIMES FOR THE ISOLATION OF MIXED 1,2,4-OXADIAZOLES, Bulletin of the Russian Academy of Sciences, Division of Chemical Sciences, 41(8), 1992, pp. 1453-1458
The reaction of perfluorinated nitriles with benz- and terephthalamido
ximes afforded amidoximimidates which can form mixed 1,2,4-oxadiazoles
in high yield under mild conditions by the action of acid fluorides o
f perfluorocarboxylic acids. The structure of the compounds obtained w
as confirmed by the methods of C-13, F-19, and H-1 NMR, and by IR spec
troscopy.
