Abstract
The kinetics of HCl-catalyzed reduction of some substituted nitrobenzenes with tin(II) chloride in 90% (v/v) aqueous ethanol at 30º have been studied. The observed rate constant of 4-methoxy-3-methyl-nitrobenzene is lower than the calculated value indicating that the 3-substituent enhances the resonance interaction between the methoxyl and nitro groups. This is due to steric enhancement of resonance (SER).
