Thiomethylation of indole and haloindoles has been achieved via their zinc salts. This one-pot reaction uses methyl disulfide as electrophile. Isolation of thiomethylated indole products in moderate yields requires the addition of a thiol (e.g., cysteine hydrochloride) during aqueous workup, facilitating the displacement of the thiomethylated product from a water-insoluble zinc salt.
