present work deals with a challenge in the synthesis of aryltrifluoromethyliodanes (ArICF3X) and develops a direct route to PhICF3Cl via a simple ligand-exchange reaction of PhI(OCOCF3)2, Me3SiCF3, and NaCl for the first time. The I–Cl bond length in PhICF3Cl supports its iodonium character, which enables an enhanced CF3-transfer capability in electrophilic S-, O-, N-, and C-trifluoromethylations as
本工作解决了芳基三氟甲基碘的合成(ArICF 3 X)的挑战,并通过PhI(OCOCF 3)2,Me 3 SiCF 3和NaCl的简单配体交换反应开发了直接通往PhICF 3 Cl的途径。第一次。PhICF 3 Cl中的I–Cl键长支持其碘鎓特性,从而在亲电子的S-,O-,N-和C-三氟甲基化以及无催化剂的三氟甲基化环化反应中增强了CF 3-转移能力。芳基腈。
