Abstract
Palladium/copper-cocatalyzed cross-coupling reactions of alkynylsilanes with aryl tosylates or mesylates afforded the corresponding unsymmetrical diarylethynes in moderate to good yields. The optimized reaction conditions to afford higher yields of cross-coupled products were found to be 5mol% of [PdCl 2(bpy)], 15 mol% of BrettPhos, and 10 mol% of Cu 1Cl in DMF as a solvent.
