A general and efficient Cp*CoIII-catalyzed C2-thiolation and C2,C3-dithiolation of indole derivatives has been achieved employingN-(aryl/alkylthio)succinimide as a thiolating reagent. This external oxidant-free method utilizes only catalytic amounts of additive and tolerates various functional groups to afford various thiolated products in good yields. Control experiments revealed the importance of the Cp*CoIII-catalyst for both C2- and C3-thiolation.

An iodine-PPh3 mediated sulfenylation of indoles in water with stable and odorless sodium sulfinates as the sulfur source is described. The reaction could afford monosulfenylated indoles in moderate to excellent yields under metal free conditions. Moreover, double C—H sulfenylation of indoles at 2- and 3-positions has also been achieved by using excess sodium sulfinates under the optimized reaction conditions.

A versatile method for the synthesis of mono- and bis-arylthioindoles via I2 catalysed direct oxidative sulfenylation of indoles with thiophenols (especially mercaptobenzoic acids) has been presented. This system features environmental friendliness, easy operation, and mild reaction conditions, and shows a broad functional group tolerance furnishing good to excellent yields.
