Direct and Convenient Synthesis of [Bis(trifluoroacetoxy)iodo]arenes from Iodoarenes

Abstract An easy, safe, and effective method for preparing [bis(trifluoroacetoxy)iodo]arenes, ArI(OCOCF3)2, in high yields from some iodoarenes are reported, using a K2S2O8/CF3COOH/CH2Cl2 system. This procedure avoids the use of high temperature and severe reaction conditions.
