A series of dithiols and disulfinic acids belonging to diphenyl bridging compounds was prepared and identified. The conditions of reduction for the corresponding sulfonyl chlorides were optimized resulting in production of the target compounds in 85-95% yields. The acidity constants of the compounds obtained were measured. A correlation between pKa and δSH, was established for thiols. Therewith the dissociation constants of thiols are readily evaluated by the chemical shift of the thiol group proton.
