Unsymmetrical diaryl-λ3-iodonium salts containing aryl triflone (Ar-SO2CF3) were designed and synthesized. X-ray crystal structure analysis of the salt indicated a T-shaped geometry at the iodine atom. The salts were found to be powerful electrophilic reagents for triflyl-arylation of C-, N-, and O-centered nucleophiles under mild conditions. Electrophilic transfer of pyridine triflone (Py-SO2CF3) to nucleophiles was also realized by the use of corresponding triflylpyridyl-aryl-λ3-iodonium salts. Selection of auxiliaries (dummy ligands) of unsymmetrical diaryl-λ3-iodonium salts is crucial for this transformation.

电三氟甲磺酰基芳基化和三氟甲磺酰基- pyridylation通过不对称芳基/吡啶基λ 3 -iodonium盐：芳基和吡啶基Triflones的合成
非对称二芳基- λ 3 -iodonium含有芳triflone（AR-SO盐2 CF 3），设计并合成。盐的X射线晶体结构分析表明在碘原子处为T形。发现该盐是在温和条件下用于以C-，N-和O-为中心的亲核试剂三氟芳基化的强力亲电试剂。吡啶triflone的电子转移（PY-SO 2 CF 3），以亲核试剂也通过使用对应triflylpyridyl芳基λ的实现3 -iodonium盐。不对称的二芳基-λ的助剂（虚设的配体）的选定3-碘盐对于该转化至关重要。
