Nucleophilic substitutions of the benzene ring proceed with aromatic amines and alcohols under mild conditions. The attack of aliphatic amines may be directed to the aromatic core as well as to the carbonyl unit leading to azocarboxamides. The benzene ring can further be modified through radicalreactions, in which the tert-butyloxycarbonylazo group enables the generation of aryl radicals at either elevated
