(Diacetoxyiodo)benzene

(????????)?? C??? ??, ??, ??

white to light yellow crystal powder

Origin

This reagent was originally prepared by Conrad Willgerod by reacting iodobenzene with a mixture of acetic acid and peracetic acid： 
C6H5I + CH3CO3H + CH3CO2H → C6H5I(O2CCH3)2 + H2O

Purification Methods

The purity of diacetoxyiodobenzene can be checked by treatment with H2SO4 then KI and the liberated I2 is estimated with standard thiosulfate. It has been recrystallised from 5M acetic acid and dried overnight in a vacuum desiccator over CaCl2. The surface of the crystals may become slightly yellow but this does not affect its usefulness. [Sharefkin & Saltzman Org Synth Coll Vol V 600 1973, Beilstein 5 IV 693.]
