Methyl p- and o-hydroxydithiobenzoates were prepared regiospecifically in a one-pot procedure from phenol methyl- and methoxymethyl, ethers, respectively. The p-hydroxy compounds were prepared by treatment of the methyl ethers with carbon disulfide, methyl iodide, and aluminum chloride. The second procedure involves ortho-metallation, carbon disulfide dithiocarboxylation, sulfur alkylation with methyl iodide, and in situ phenol deprotection with aluminum chloride/methyl iodide.

Rhodium-catalyzed transformation of alkyl aryl sulfides into arylboronic acid pinacol esters via C–S bond cleavage is reported. In combination with transition-metal-catalyzed sulfanyl group-guided regioselective C–H borylation reactions of alkylthioarenes, this method allows the synthesis of a diverse range of multisubstituted arenes.
