Pyridine → 21H,22H-Porphine

Participants

Reaction Steps

The synthesis was performed in a three-necked flask under nitrogen. 50 mg of mezo-tetra(4-carboxyphenyl)porphine (4CP) was dissolved in 5 ml of dry DMSO, the catalysts, i.e. 120 μl of pyridine and 30 μl of isobutyl chloroformate, were added and after 5 minutes a suspension of 0.5 g Cloisite 30 B in 15 ml of dry DMSO was added. The reaction mixture was mixed at 70° C. for 4 hours. The product obtained was filtered on a Buchner funnel with a sintered glass disc and washed with methanol till the transparent filtrate was obtained and then the product was dried in a vacuum dryer. A green powder was obtained.
