Attempts of Valence Isomerization on Substituted 2‐Phenyl‐4‐phenylazo‐benzotriazoles: Limits of the Boulton‐Katrizky Rearrangement Substituted 2‐phenyl‐4‐phenylazo‐benzotriazoles are prepared and their UV./VIS., 1 H‐NMR. and mass spectra discussed. A thermic or photochemical valence tautomerization according to the Boulton‐Katritzky rearrangement could not be proved.
