Abstract

A few substituted aryldithiaphenols have been synthesized and their acid dissociations, NMR chemical shifts and UV spectra have been determined. The relatively stronger acidic nature of p-aryldithiaphenols over that of the meta-isomers is interpreted as being caused by the 3d-orbital resonance effect of the aryldithia group.
