The kinetics of the reaction of a series of 2-nitro-3-bromo-5-X-thiophenes with sodium thiophenoxide in methanol were determined. The plot of log k against σ-values gave ρ-value + 4.51 at 20°. Good correlation was observed pointing out the validity of the Hammett relationship for reactions occurring directly on the thiophene ring at the β-position with respect to the heteroatom.
