Alkaline ferricyanideoxidation of 4-arylazo-2,6-di-t-butylphenols (I) gave molecular nitrogen, diphenyl derivatives (VI), 2,6-di-t-butyl-p-benzoquinone-N-(3′,5′-di-t-butyl-4′-hydroxyphenyl)arylhydrazone (V) and red tarry compounds. Picryl derivative of phenol (I) gave 2,6-di-t-butyl-p-benzoquinone-picrylanil (X) instead of hydrazone (V). The reaction path was studied on the basis of isolated compounds
