3-Alkylphenols derived from renewable natural resources have been used to synthesise thiobisphenols by reaction with sulfur dichloride. In contrast to previous work, we have found that 3-alkylphenols give isomeric products, the major symmetrical, the 4, 4 '-thiobis compound, the minor symmetrical, 2, 2 '-thiobisphenol, and some of the believed unsymmetrical isomer. The role of the solvent and catalyst have been studied in the ...
