ABSTRACT:
A process is provided for the formation of 4,4'-monothiodiphenolic compounds, in high yields, and in a selective manner, through the use of a novel reaction system. More specifically, a nonsterically hindered phenol and sulfur dichloride are reacted in the presence of initiation promoter and solvent portions, respectively, to produce the above 4,4'-monothiodiphenolic product.
