Abstract
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.Keywords
