Palladium-catalyzed annulation of 1-alkynylphosphine sulfides with 2-iodoanilines followed by desulfidation affords 3-substituted 2-indolylphosphines. This annulation/desulfidation sequential protocol offers a conceptually new approach to bulky heteroarylphosphines.

A novel four-step domino process for the synthesis of 3-[2-(aryl/alkylsulfonyl)ethyl]indoles starting from readily available 2-iodoanilines is reported. The domino reaction is based on the intramolecular palladium-catalyzed α-arylation of sulfones, which was combined with both intermolecular aza-Michael and Michael addition reactions using vinyl sulfones as the electrophile. The domino process produced

A cleaner and greener method of synthesis of 3H-benzothiazole-2-thione is being reported in this communication. In this method, various o-iodoaniline derivatives are reacted with carbon disulfide in the presence of Cs2CO3 and tetramethyl ammonium bromide (TMAB) to give 3H-benzothiazole-2-thione and itsderivatives in higher yields.
