Kinetics of hydrolysis of aromatic mono- and disulfonyl chlorides

A continuous polarografic method of recording instantaneous concentrations of - SO2Cl groups in an aqueous acetic acid system containing CH3CO2Na has been elaborated.Ten model monosulfonyl chlorides underwent hydrolysis according to pseudo-first order kinetics (20percent H2O, 80percent v.v.CH3CO2H, 0.5 mol/dm3 CH3CO2Na).Plots of hydrolysis for seven disulfonyl dichlorides with different number of - CH3 groups have been determined.Pseudo-first order rate constants for two consecutive reactions of hydrolysis (k1 and k2) have been computed and the influence of -SO2Cl and -SO3- groups on the reactivity of the second group - SO2Cl has been discussed.The mechanism of nucleophilic substitution has also been discussed.

Reactions of 1,2-Benzenedisulfinic Anhydride

1,2-Benzenedisulfinic anhydride (2) is the first isolable example of an aromatic sulfinic anhydride.Its reaction with simple amines and alcohols is straightforward, the nucleophile (NuH) attacking one of the sulfinyl groups in 2 and forming the ring-opene
