To probe the substrate scope of the reaction, more aryl iodides and bromides were chosen to react with phenylactylene using 1 mol % catalyst 3a with 2 eq K2CO3 in DMSO (2 mL) in air (Table 3). The results showed that 3a could not only catalyze the cross-coupling reaction of phenylacetylene with more reactive aryl iodides, but also could catalyze the reaction in good to moderate yield (55% -86%) with less reactive aryl bomides in the absence of copper co-catalysis. To an oven-dried 50 mL of r.b.f. containing 2a , PdCl2 , K2CO3 and NaBr with a septum was injected into pyridine (5 mL) under argon. |
