Tetraphenylporphyrin Synthesis Essay

Nickel tetraphenylporphyrin (Ni-TPP) is one of the model metal compounds used for the study of hydrodemetalization (HDM). It is also possible to introduce aluminum into the framework of MCM-41 during hydrothermal synthesis or by post-synthetic alumination to generate some acid sites. This novel material has been reported to have potential usage in hydrotreating such as hydrocracking (6-8.

Microwave Synthesis of 5,10,15,20- Tetraphenylporphyrin Essay .Microwave Synthesis of 5. 5,10,15,20, tetraphenylporphyrin was prepared, from four molecules each of pyrrole and benzaldehyde. A method of porphyrin synthesis that is solventless is carried out on a solid support. The two reagents, pyrrole and benzaldehyde, react on the support under irradiation in a conventional microwave.The nitrosyl complex of ferrous tetraphenylporphyrin 1-methylimidazole (F(II). The inorganic scientific community has been deeply interested in the synthesis of model complexes for the B 12 cofactors since the elucidation of the structure of vitamin B 12 in the 1960s. Indeed, as small-molecule cofactors, coenzyme B 12 and its organocobalt relatives may serve as “model” complexes.Oxidation of tetraphenylporphyrinogen to tetraphenylporphyrin. It is widely accepted that tetraphenylporphyrinogen is the key intermediate in the synthesis of tetraphenylporphyrin. The oxidation of tetraphenylporphyrinogen by O 2 in the atmosphere (Scheme 1)15,23 was a competitive procedure which formed the desired porphyrin (TPPH 2) and.


Synthesis of meso-tetraphenylporphyrin: The meso-tetraphenylporphyrin was synthesized by reaction of pyrrole (0.4 mL) with benzaldeh yde (0.53 mL) and 0.05 g of p-toluene sulfonic acid in a Pyr ex bottle under micr owav e irradiation at 2 min inter vals f or 10 min.
