Aromatic Sulphonation. Part 76. Sulphonation in Sulphuric Acid of ω-Phenylalkanes containing the NH3(1+), NMe3(1+), or NO2 Substituent at Position 1. Comparison of the Side-chain NH3(1+), NMe3(1+), NO2, SO3H, and OSO3H Substituent Effects

The sulphonation of a series of ω-phenylalkanes containing at position 1 the NH3(1+), NMe3(1+), and NO2 substituent in concentrated sulphuric acid at 25 deg C has been studied, and partial rate factors for the mechanism with H2S2O7 as sulphonating entity are reported.The limiting values of the partial rate factors for para- and meta-substitution are equal to those of the corresponding 1-phenylalkanes, but the limiting value for ortho-substitution is smaller.The variation of the degree of ortho-substitution with the nature of the substituent is taken to indicate the operation of an inductive effect in addition to the now generally accepted field effect.
