Microwave synthesis of 5,10,15,20- tetraphenylporphyrin abstract: in this green chemistry experiment of 5,10,15,20-tetraphenylporphyrin was synthesized from benzaldehyde and pyrrole using microwave irradiation to heat the reactants, the liquid reactants are absorbed on a solid support, silica gel, which acts as a lewis acid catalyst to facilitate the reaction. Synthesis, crystal structures, and redox potentials of 2,3,12,13-tetrasubstituted 5,10,15,20-tetraphenylporphyrin zinc(ii) complexes yuichi terazono, brian o patrick. Synthesis biosynthesis [ edit ] in non-photosynthetic eukaryotes such as animals, insects, fungi, and protozoa , as well as the α-proteobacteria group of bacteria, the committed step for porphyrin biosynthesis is the formation of δ-aminolevulinic acid (δ-ala, 5-ala or dala) by the reaction of the amino acid glycine with succinyl-coa from the.
The simplest synthesis of the porphyrin complexes is that of 5,10,15,20-tetraphenylporphyrin (tpp), which synthesis consists of simply heating a mixture of benzaldehyde and pyrrole, absorbed on silica, in a microwave for about 10 minutes.

A facile first synthetic strategy to construct novel π-extended β,β′-fused nickel(ii) pyrrolo[1,2-a]pyrazinoporphyrins has been developed via a pictet–spengler reaction of newly prepared nickel(ii) 2-amino-3-(pyrrol-1-yl)-5,10,15,20-tetraphenylporphyrin with various aromatic, aliphatic or heterocyclic aldehydes in the presence of 10 mol. Two techniques in the synthesis of porphyrins, phthalocyanines and related compounds have attracted a considerable amount of attention in recent years: the use of microwave irradiation instead of conventional thermal heating and utilization of ionic liquids instead of ordinary solvents.
