The alkaline hydrolysis of substituted phenyl benzenethiolsulfonates has been investigated. The rate was found to be first order with respect to both hydroxide and ester. The second order rate constant for the unsubstituted ester was found to be 3.2×103 M−1 sec−1 (water 45°C). The Hammett ρ values were found to be ρX,Y=H=2.1 and ρY,X=H=1−1 for (Remark: Graphics omitted.) respectively. The reactivities of three esters, i. e. phenyl benzenethiolsulfonate, -thiolsulfonate and -sulfonate were compared.
