An interesting manganese-catalyzed Sonogashiracoupling reaction of aryl iodides has been developed. With PEG-400 as the green solvent and under mild reaction conditions, a variety of diarylacetylenes were obtained in moderate to good yields.
Decyl(Tri-<i>Tert</i>-Butyl)Phosphonium Tetrafluoroborate/Palladium Acetate: An Effective Catalyst for Cross-Coupling Reaction of Arylbromides with Phenylacetylene in Copper-Free Conditions
The phosphonium salts with sterically hindered cation and noncoordinating anion can be used as phase-transfer reagent in the Sonogashira cross-coupling reaction allowing copper- and amine-free protocol. The reactions proceed under mild conditions with good yields.
