Polar Effects of Substitutents on the Reaction Rates of 4-R- and 5-R-2-Nitrochlorobenzenes with Piperidine in Benzene
The rate constants for the reaction of fourteen 4-R- and of twelve 5-R-2-nitroehlorobenzcncs with piperidine in benzene have been determined. The reaction follows the Hammett relationship log kR/kH = σ*ρ with a ρ-value of +3.80. Differences in rates are mainly determined by differences in activation...

| Sumario: | The rate constants for the reaction of fourteen 4-R- and of twelve 5-R-2-nitroehlorobenzcncs with piperidine in benzene have been determined. The reaction follows the Hammett relationship log kR/kH = σ*ρ with a ρ-value of +3.80. Differences in rates are mainly determined by differences in activation energies. © 1962, American Chemical Society. All rights reserved. |
