The present work deals with a challenge in the synthesis of aryltrifluoromethyliodanes (ArICF 3 X) and develops a direct route to PhICF 3 Cl via a simple ligand-exchange reaction of PhI (OCOCF 3) 2, Me 3 SiCF 3, and NaCl for the first time. The I–Cl bond length in PhICF 3 Cl supports its iodonium character, which enables an enhanced CF 3 ...
