Inter- and Intramolecular Anodic Nucleophilic Substitutions of Porphyrins. Reactivity of the resulting products

2020

This manuscript presents the functionalization of porphyrins by anodic nucleophilic substitution (SNAn). After an introduction describing generalities on porphyrin, the 2nd chapter deals with the 2-step synthesis of primary aminoporphyrins. The 1st electrochemical step consists in oxidizing the porphyrin at the 1st oxidation potential in the presence of pyridine. The formed pyridinium-porphyrin is then transformed into an amine by opening the pyridinium fragment by nucleophilic attack of piperidine.The 3rd chapter presents the synthesis and redox reactivity of porphyrins substituted with one (or several) aromatic groups carrying an imine function (thiopyrimidine, quinoline and aminopyridine…
