A nickel-catalyzed amination to access diarylamines has been developed through C?CN bond activation of aryl nitriles with anilines. In this developed catalytic protocol, various aromatic and heteroaromatic nitriles could be utilized as the electrophiles to couple with substituted anilines. A diversity of diarylamines were obtained in 15–95% yields. (Figure presented.).

The first general palladium-catalyzed amination of aryl phosphates is described. The combination of MorDalPhos with [Pd(?-cinnamyl)Cl]2 enables the amination of electron-rich, electron-neutral, and electron-poor aryl phosphates with a board range of aromatic, aliphatic, and heterocyclic amines. Common functional groups such as ether, keto, ester, and nitrile show an excellent compatibility in this reaction condition. The solvent-free amination reactions are also successful in both solid coupling partners. The gram-scale cross-coupling is achieved by this catalytic system.

The hydroxyl groups of naphthol and tautomerizable phenol derivatives have been substituted by O-, S-, N-, and C-centered nucleophiles under solvent-free reaction conditions. The products are generated in good to excellent yields. para-Toluenesulfonic acid exhibits the best catalytic activity compared to other Bronsted acids. Experimental observations suggest that the reaction proceeds through the intermediacy of the keto tautomer of naphthol. Nucleophilic addition to the carbonyl group followed by elimination of water generates the desired product. The present methodology provides access to substituted naphtho[2,1-b]furan derivatives. The products generated using N-centered nucleophiles can be further transformed to important classes of organic molecules such as benzocarbazole and imidazole derivatives.
