The demetalation of a series of (5,10,15,20-tetraphenylporphyrinato)iron(III) complexes having bulky substituents at the o-positions of phenyl rings was studied in acetic acid in the presence of iron(II) chloride and HCl.The reaction occurred simultaneously with the reduction of Fe(III) porphyrin to Fe(II) porphyrin, since no demetalation was observed without iron(II) chloride.The pseudo-first-order rate constants, which were determined spectrophotometrically, decreased with an increase in the bulkiness of the o-substituents on the phenyl rings.The atropisomeric structures of the products were determined by high-resolution NMR measurements.

New porphyrin derivatives having alkyl phosphorylcholine groups as amphiphilic moieties and their iron complexes were prepared.Based on the hydrophobic-hydrophilic balance, some of the synthesized complexes were efficiently embedded in the bilayer of phos
