Abstract
In the presence of very low amounts of palladium(II) β-oxoiminatophosphane complexes, various aryl iodides and bromides were efficiently coupled with terminal alkynes at low temperatures. The mild, efficient, aerobic, solvent-free, and copper-free conditions also allowed Sonosgahira reactions of aryl chlorides.
