A mini-review covers the results obtained by the authors in porphyrin modifications using Pd and Cu-catalyzed amination of halogenophenyl substituted porphyrins. Amination using primary and secondary linear and cyclic amines and diamines, formation of polymacrocyclic conjugates of azaand diazacrown ethers and diazacrown ether-based cryptands with porphyrins are addressed. Synthesis of diporphyrin and triporphyrin systems via Pd-catalyzed amination and Cu-catalyzed “click” reactions are discussed.
