Kinetics of the reactions of 2,4-dinitrophenyl aryl sulphides sulphoxides and sulphones with hydroxide ion in 80 % [v/v] ethanol-water

The effect of substituent for the reactions of 2,4-dinitrophenyl aryl sulphoxide [la], sulphones [2a-i] and sulphides [3a-h] with hydroxide ion in 80% ethanol-water [v/v] at 25C was investigated. The relative mobility of thioaryl, sulfinylphenyl and sulfonyl aryl leaving groups was also discussed
