Transformations of Less-Activated Phenols and Phenol Derivatives via C–O Cleavage
Chemical Reviews, 2020Employing phenols and phenol derivatives as electrophiles for cross-coupling reactions has numerous advantages over commonly used aryl halides in terms of environmental-friendliness and sustainability.

Formal Direct Cross‐Coupling of Phenols with Amines
Angewandte Chemie - International Edition, 2015The transition-metal-catalyzed amination of aryl halides has been the most powerful method for the formation of aryl amines over the past decades. Phenols are regarded as ideal alternatives to aryl halides as coupling partners in cross-couplings.
