A tetra-: N -butylammonium iodide mediated reaction of indoles with Bunte salts: Efficient 3-sulfenylation of indoles under metal-free and oxidant-free conditions

Article abstract of DOI:10.1039/c6ob01528j

A highly efficient tetra-n-butylammonium iodide (TBAI) triggered procedure for 3-sulfenylation of indoles with Bunte salts is demonstrated. This protocol provides a simple strategy to prepare 3-alkylthioindoles and 3-arylthioindoles from the corresponding indoles under metal-free and oxidant-free conditions.
