[Effect of aniline and hydrazine derivatives on reversible oxygen addition in model systems of cobalt complexes of etioporphyrin and alpha, beta, gamma, delta-tetraphenylporphine]. / Izuchenie vliianiia anilina i proizvodnykh gidrazina na obratimoe prisoedinenie kisloroda v model'nykh sistemakh kobal'tovykh kompleksov étioporfirina i al'fa, beta, gamma, del'ta-tetrafenilporfina

The influence of aniline and hydrazine derivatives on the reversible oxygenation of cobaltous complexes of etioporphyrin I and alpha,beta,gamma,delta-tetraphenylporphin has been studied by means of ESR and electronic spectra. The formation of stable six-coordinated complexes with the said reagents prevents the oxygenation. The excess of hydrazines cause the destruction of porphyrin nucleus. The formation of intermediate dihydroporphyrins (chlorins) has been noticed.
