Effect of a Nitrogen-Containing Base on the Kinetics of Formation of the Zinc–Octa(m-trifluoromethylphenyl)porphyrazine Complex in Benzene

摘要

The effect additions of n-butylamine, tert-butylamine, piperidine, and morpholine have on the kinetics of the complexation of zinc acetate with octa(m-trifluoromethylphenyl)porphyrazine in benzene is studied. A possible scheme of the complexation reaction is proposed. It is established that the rate of the reaction slows with the branching of the hydrocarbon chain in the amine, and it grows along with the pK_a of the nitrogen-containing base.
