Reaction of 3-AR(ALK)oxysulfolanes with amines
On the basis of data on the kinetics of the hydrolysis of 3-aroxysulfolanes in aqueous solutions of tertiary amines and in acetonitrile it is shown that the elimination of phenols is subject to specific base catalysis and occurs via an (ElcB)R carbanion mechanism. The exchange of aroxy and alkoxy groups of sulfolanyl ethers on reaction with nucleophilic reagents is explained by an elimination-addition scheme.
