nitroaromatics

Acid-promoted condensation of 4- tert-butyl-2-hydroxylaminoanisole with p- tert-butylphenol resulted in the formation of 5,5′-di- tert-butyl-2,2′-dihydroxydiphenylamine upon demethylation with BBr 3. Protection of the acidic phenol unit was required to isolate the acid labile N-arylhydroxylamine intermediate. Graphic
