Abstract

A method of preparing dimethylsulfoxide and dimethylsufones of substituted benzoic acid of formula (IX) **(See formula)** where R1 is one or more alkoxy groups, preferably containing 1 to 4 carbon atoms (eg methoxy, ethoxy, n-propoxy, t-butoxy), R2 is an optional substituent, such as a halogen atom, especially chlorine, bromine or iodine, an alcohol group, preferably containing from 1 to 4 carbon atoms (eg, methyl, ethyl, propyl or butyl), an amido group or an amino group, and n is 1 or 2, which comprises making react a benzoic acid derivative of formula (VIII) **(See formula)** where R1 and R2 are as defined above and R is an alcohol group preferably having 1 to 4 carbon atoms, with a compound of formula (VII) CH3.SOn.CH3 (VII) where n is 1 or 2, in the presence of a base, strong enough to provide the appropriate carbanion in a suitable amount, for the reaction.
