Polar and steric effects of substituents in aromatic nucleophilic substitution. Reactions of 4-, 5-, and 6-substituted 1-chloro-2-nitrobenzenes with sodium thiophenoxide in methanol
The kinetics of the reactions of 4-, 5-, and 6-substituted 1-chloro-2-nitrobenzenes with sodium thiophenoxide in methanol have been determined, and the thermodynamic parameters, energy and entropy of activation, calculated. For the 5-substituted series a plot of log k against σ-values gave a ρ-value...
