Abstract
Substituted alkoxybenzenes are obtained by reacting a substituted hydroxybenzene with dimethyl sulphate or diethyl sulphate and an alkali metal carbonate at a temperature at which the mixture forms a stirrable suspension of the carbonate in the fluidised organic components. The process allows quantitative yields since a solvent is dispensed with in the reaction.
