      Reversed-phase thin-layer chromatography of N-oxides on C-18 and cyanopropyl (CN) bonded silica gel

      J. Planar Chromatogr. 2, 203-206 (1989).

Using methanol-water solvent systems containing up to 60% methanol the N-oxides had higher Rf values than their respective parent compounds. At concentrations of methanol of 80% or more the order of migration was reversed. Separation of critical pairs was possible by careful selection of one or other of the phases.
