The complex formation of β-octaethylporphyrin, β-octaethyl-meso-monophenylporphyrin, β-octaethyl-meso-tetraphenylporphyrin, meso-diphenylporphyrin, meso-triphenylporphyrin, and meso-tetraphenylporphyrin with Zn(II), Cu(II), Co(II), and Mn(II) acetates and chlorides in dimethylformamide, dimethylsulfoxide, pyridine, acetic acid, and a chloroform–methanol 1 : 1 mixture has been studied by means of spectrophotometry. The observed regulations are in line with the concept of chemical reactivity of the N–H bonds in porphyrins of different complexity.

Two series of synthetic porphyrins with a progressively increasing degree of macrocycle deformation were studied. The equilibrium constants for the extra coordination of piperidine and N-methylimidazole by zinc complexes of spatially distorted porphyrins, octaethylporphyrin derivatives, and spatially hindered and planar analogs were determined. It was found that the steric distortion of the porphyrin nucleus destabilizes the extra complexes. Copyright
