A palladium(II) complex which catalyzes the Sonogashira coupling reaction efficiently under aerobic condition and a method of employing the palladium(II) complex to synthesize internal alkynes. The palladium(II) complex is an effective catalyst for the coupling reactions of aryl iodo and diiodo compounds with unactivated alkyl alkynes and terminal dialkynes to produce various novel symmetrical dialkynes and disubstituted internal alkynes in excellent yields.
