Arenesulfinyl chlorides (4-XC6H4S(O)Cl; X = H, CH3, F, Cl, Br) react with activated zerovalent zinc in benzene at 6 to 8 deg C to give symmetrical S-aryl arenesulfonothioates (thiosulfonates) in good to excellent yields. 2- and 3-substituted arenesulfinyl chlorides (X=Cl, CH3) give a mixture of products (disulfide, thiosulfinate, and/or thiosulfonate). 2,4,6-Triisopropylbenzenesulfinyl chloride reacts with zinc in 1,2-dimethoxyethane to give S-(2,4,6-triisopropylphenyl) 2,4,6-triisopropylbenzenesulfinothioate and bis(2,4,6-triisopropylphenyl) disulfide.Possible mechanisms for the reaction, the 1H and 13C NMR spectra and the chemical ionization and electron impact mass spectra of the thiosulfonates are discussed.The para carbon substituent chemical shifts (Cp-SCS) for the thiosulfonates and for symmetrical diaryl disulfides have been subjected to several dual substituent parameter (DSP) correlations. Key Words: S-aryl-arenesulfonothioates (thiosulfonates); arenesulfinyl chlorides; 1H and 13C NMR; mass spectrometry; substituent shift parameters.
