Halotoluenes and haloanisoles (F, Cl and Br) have been sulphonylated using benzenesulphonyl chloride and anhyd.AlCl3, and the products recovered and analysed by proton and carbon-13 NMR spectra.Formation of a minor product is found in most of the halotoluenes and in m-haloanisoles.Halogens predominantly orient the substitution in halotoluenes and methoxy group in haloanisoles.Fluorine behaves differently from other halogens in p-fluorotoluene and m-fluoroanisole.This anomaly has been discussed.Proton and carbon-13 NMR spectral data for some diphenyl sulphones obtained in benzenesulphonylation reaction have been reported.
