Abstract

N:N1 - Disubstituted - 4:41 - bipyridylium salts are prepared by reaction of an N:N1-disubstituted 1,11,4,41 - tetrahydro - 4:41-bipyridyl with a carbon compound containing a labile halogen (excluding fluorine) atom. Specified carbon compounds include carbon tetrahalides, bromotrichloromethane, dichlorodibromomethane, bromoform, iodoform, methylene iodide, hexachloroethane, hexachloropropene, 1:1:1 - trifluoro - 2: - dibromo-2-chloroethane and hexachloroacetone, The substituted tetrahydrobipyridyl starting materials may carry, e.g. alkyl or carbamylalkyl substituents on the nitrogen atoms and may also carry, e.g. alkyl substituents on the carbon atoms of the pyridine ring(s), The reaction may be carried out in an inert solvent and many of the latter are exemplified.
