N-Halogeno-compounds. Part 7. Synthesis and Iodine-catalysed Rearrangement to 6-Chloroimino-1-azacyclohexadienes of 4-Substituted 2-(Dichloroamino)-3,5,6-trifluoropyridines

Electrophilic chlorination of the fluorinated 2-aminopyridines 4-X*C5F3N*NH2-2 with t-butyl hypochlorite gave the 2-(dichloroamino)-compounds 4-X*C5F3N*NCl2-2; these isomerized to mixtures of the corresponding 3-chloro-6-chloroimino-1-azacyclohexa-1,4- (predominantly) and 5-chloro-6-chloroimino-1-azacyclohexa-1,3-dienes when treated with iodine. 'Spontaneous' formation of 3-chloro-6-chloroimino-2,3,5-trifluoro-4-methyl-1-azacyclohexa-1,4-diene occurred following chlorination (ButOCl) of 2-amino-3,5,6-trifluoro-4-methylpyridine. 3-Chloro-6-chloroimino- 3,5-difluoro-4-X-2-oxo-1-azacyclohex-4-enes (X = H, Me, or Cl) were obtained by displacement of fluorine from the corresponding 3-chloro-6-chloroimino-2,3,5-trifluoro-1-azacyclohexa-1,4-dienes with water; hydrolysis of 4,5-dichloro-6-chloroimino-2,3,5-trifluoro-1-azacyclohexa-1,3-diene provided 4,5-dichloro-6-chloroimino-3,5-difluoro-2-oxo-1-azacyclohex-3-ene.Pyrolysis of the 2-(dichloroamino)pyridines 4-X*C5F3N*NCl2-2 gave the azo-compounds 2,2'-2.The 19F n.m.r. spectra of the chloroimino-1-azacyclohexadienes have been analysed.
