catalyst in the formation of C–C bonds. The coupling of terminal alkynes formed gem-1,3-enynes as the only reaction products. Aromatic alkynes can be synthesized from the coupling of terminal alkynes and haloaromatic compounds (Sonogashira coupling). The phosphinito palladium(II) complex also catalyses the coupling between acyl chlorides and terminal alkynes (Sonogashira coupling), furnishing ynones in excellent
空气稳定的膦基钯(II)配合物(Ph1-Phoxide)被发现是形成CC键的有效催化剂。末端炔偶联形成宝石-1,3-烯炔作为唯一的反应产物。芳炔可以由末端炔与卤代芳族化合物的偶联(Sonogashira偶联)合成。膦基钯(II)配合物还催化酰氯与末端炔烃之间的偶联(Sonogashira偶联),从而以优异的产率提供了炔酮。
