Investigation of Kinetics of Coordination of meso-Nitro-Substituted Derivatives of 5-Phenyl-β-octaalkylporphine with Palladium Acetate

详细

Kinetics of the formation reactions of palladium complexes of meso-nitro-substituted 5-phenyl-β- octaalkylporphine derivatives in the Pd(OAc)₂–acetonitrile system at 303–323 K was studied by spectrophotometry. The kinetic parameters of the formation reaction of complexes of porphyrins under study with palladium and zinc previously prepared, as well as their corresponding fluorescence spectra, were subjected to a comparative analysis. The parameters of electron absorption spectra of all palladium porphyrinates obtained were determined.
