Abstract: The title compound, trans-[PdBr(C₇H₂F₅O₃S)(C₁₈H₁₅P)₂], was obtained in quantitative yield by oxidative addition of the electrophile 1-bromo-3,4-difluoro-2-(trifluoromethylsulfonyloxy)benzene to Pd(PPh₃)₄ in toluene, and was recrystallized from a mixture of tetrahydrofuran and pentane. The structure was resolved by single-crystal X-ray diffraction and turned out to be one of the few known examples among complexes of general formula trans-[(PAr₃)₂Pd(X)Ar'] that exhibit double - stacking intramolecular interactions (three aromatic rings are piled above each other).
