A series of arylamino- and alkylamino-substituted diphenylporphyrins and tetraphenylporphyrins were efficiently synthesized by reactions of brominated porphyrin precursors with amines via palladium-catalyzed amination. The multiple amination reactions are general and suitable for a variety of amines, affording the desired aminoporphyrins in good to excellent yields. Examples include aromatic and aliphatic amines, primary and secondary amines, electron-rich, -neutral, and -poor amines as well as heteroaromatic amines and imines.
