3-[2-(N-p-Toluenesulfonyl)aminophenylthio]prop-1-yne, reacted with aryl iodides in the presence of Et3N in THF solution with (PPh3)(2)PdCl2 (3 mol%) and CuI (40 mol%) at room temperature for 8 h followed by reflux for 20 h to yield diaryl sulfides by a depropargylation and S-arylation reaction.

3-[2-(N-p-Toluenesulfonyl)aminophenylthio]prop-1-yne (4) reacted with aryl iodides 5-14 under palladium-copper catalysis to afford (2-arylthio)-p-toluenesulfonanilide (15-23) in moderate to good yields (54-64%) through unusual depropargylation and S-arylation reactions.
