Sulphuryl chloride as an electrophile. Part II. Substituted m-di-methoxybenzenes
Abstract
The rates of reaction of sulphuryl chloride with a number of derivatives of m-dimethoxybenzene in chlorobenzene show good correlation with the Hammett equation. The high value of the reaction constant (ρ=–4·0) confirms the heterolytic nature of the rate-determining step; further evidence of this mechanism is presented. Details are given for the preparation of pure derivatives of m-dimethoxybenzene.
