Hydrolysis of 16 compounds ClO2S-Ar-B-Ar-SO2Cl (B, bridge) in 20percent H2O, 80percent v/v CH3CO2H, 0.5 mol dm-3 CH3CO2Na at 298.15 K has been investigated by a polarographic method.From plots of the hydrolysis, pseudo-first-order rate constants for two consecutive reactions have been computed and the influence of -SO2Cl groups, bridges B, and SO3(1-) groups on the reactivity of -SO2Cl groups has been discussed.The ratio of rate constants k2/k1 ranges from 0.45 to 30, depending on the structure.Log (k1/(2kH)) correlated linearly with ? m,p -B-C6H5 and log (k2/k1) correlated linearly with ΔpK for the analogous diamine series H2N-Ar-B-Ar-NH2.
