Abstract
The reduction of manganese(III) porphyrins by hydrazine (L) was investigate d by stopped-flow techniques. The mechanism of the reaction has been propos ed based on the experimental results; the relationship between pseudo-first -order rate constants with the concentration of L. Calculated activation pa rameters showed that the pre-equilibrium step was exothermic and the reduct ion step endothermic. Substituent effects in the phenyl rings on the two st eps have been examined.
