Abstract

The effect of substituents on the spectral behavior of some arylthiomethyl benzoic acid derivatives, the corresponding sulfoxides and sulfones were studied. The chemical shifts of ortho hydrogen of benzyl moieties gave linear correlations with Hammett constants for acid sulfides and concave curves for sulfide esters. The effect of substituents on the conformation of sulfides were discussed.
