Straightforward Syntheses That Avoid Scrambling of meso-Substituted [28]Hexaphyrins
Plamont, Rémi,Balaban, Teodor Silviu,Canard, Gabriel
, p. 593 - 599 (2017)
A two-step synthesis of meso-substituted [28]hexaphyrins in an aqueous medium was developed and optimized, and scrambling processes are avoided despite the use of a high acid concentration. The efficiency of this procedure relies on the nature of the star
Synthesis of meso-substituted corroles and porphyrins using iodine as a catalyst
Chauhan, Shive M S,Dandia, Anshu

Abstract: Different types of corroles and porphyrins are synthesized from substituted aldehydes and pyrrole. The current synthetic method involves iodine as catalyst and proceeds at room temperature itself. By varying the amounts of reactants (i.e., pyrrole and aldehydes), the corrole and porphyrins were obtained in good to excellent yields. These products were characterized by 1H-NMR, UV-visible, and HRMS techniques. The reaction approach utilizes the readily available pyrrole and substituted aldehydes as starting materials and makes this reaction highly attractive in diversity-oriented synthesis.
