A study of the reaction of cis-[PdRf2(AsPh3)2] (Rf = 3,5-C6Cl2F3) with ISnBu3 (that is the reversal of the natural Stille reaction of [PdRfI(AsPh3)2] with RfSnBu3) allows for the observation of cis-[PdRf2(AsPh3)(ISnBu3)], the expected intermediate from a cyclic transmetalation in the direct Stille reaction, thus providing experimental support to the operation of cyclic transmetalation pathways.
对顺式-[PdRf₂(AsPh₃)₂]（Rf = 3,5-C₆Cl₂F₃）与ISnBu₃的反应（即[PdRfI(AsPh₃)₂]与RfSnBu₃的天然Stille反应的逆反应）进行研究，能够观察到顺式-[PdRf₂(AsPh₃)(ISnBu₃)]，它是直接Stille反应中循环转金属化预期的中间体，从而为循环转金属化途径的运行提供了实验支持。
