Rates of reaction of methansulforny1 chloride with various substituted anilines have been measured in methanol.
Substituent effects in aniline are found to be linearly correlated with pka (BrΦnsted relation with β=0.83) and Ρ=-2.45) respec tively.
The results are interpreted in terms of degree of bond-formation at the transition state, which was found to have progressed relatieely further.
The rates for o-methylaniline deviated from the BrΦnsted plot established by meta and para substituted aniline because of a steric effect of ortho position in aniline.
Activation parameters, △H and △S have also been determined.
The enthalpy of activation showed a regular variation in that electron donation substituents in the p-substituted aniline decrease △H and increase the negative value of △H
