合成了标题配合物3，并用x射线晶体学对其进行了表征。在THF中，它通过非解离机制与芳基三氟酸盐和碘化物氧化加成。在与三氟酸苯的反应中检测到微量的Heck加成产物肉桂酸甲酯，并对碘苯的直接氧化加成产物进行了表征。在体系中加入卤化物或乙酸盐对芳基三氟酸酯的氧化加成速率影响不大，但产生中性芳基钯（II）配合物。锂盐或铕盐的加入提高了反应速率，对Eu(OTf)3的影响最为明显，可能是通过促进竞争解离途径。
The title complex 3 has been synthesized and characterized by X-ray crystallography. It undergoes oxidative addition with aryl triflates and iodides by a nondissociative mechanism in THF. The Heck addition product methyl cinnamate was detected at traces from the reaction with phenyl triflate, and from iodobenzene the direct oxidative addition product was characterized. The addition of halides or acetate salts to the system led to modest effects on the rate of oxidative addition of aryl triflates, but resulted in neutral arylpalladium(II) complexes. Addition of lithium or europium salts enhanced the reaction rate, the effect being most pronounced with Eu(OTf)3, possibly through promotion of a competing dissociative pathway.
