[Hydroxy(tosyloxy)iodo]benzene Usage And Synthesis

Chemical Properties Pale yellow crystalline powder

Uses Versatile synthetic reagent in phenyliodination and/or tosylation of a range of organic substrates; in oxidative transformations including oxidative rearrangements.

Purification Methods Possible impurities are tosic acid (removed by washing with Me2CO) and acetic acid (removed by washing with Et2O). It is purified by dissolving in the minimum volume of MeOH, adding Et2O to cloud point and setting aside for the prisms to separate [Koser & Wettach J Org Chem 42 1476 1977, NMR: Koser et al. J Org Chem 41 3609 1976]. It has also been crystallised from CH2Cl2 (needles, m 140-142o) [Neiland & Karele J Org Chem, USSR (Engl Transl) 6 889 1970].
