Hypervalent iodine compounds have proved to be very useful reagents to bring about various oxidative transformations including (i) α-functionalization of carbonyl compounds, (ii) oxidation of phenols, and (iii) oxidative rearrangement of ketones and α,β- unsaturated ketones. These reactions find interesting applications in the development of newer and convenient approaches for the synthesis of flavonoids. This review focuses on the use of most common three hypervalent compounds, namely iodobenzene diacetate, [hydroxy(tosyloxy)iodo]benzene, and [bis-trifluoroacetoxy(iodo)]benzene in the synthesis of cis/trans-3-hydroxyflavanones, 3-hydroxyflavones (flavonols), flavones, isoflavones and related compounds.

We report a convenient and practical method for the preparation of nonexplosive cyclic hypervalent iodine(III) oxidants as efficient organocatalysts and reagents for various reactions using Oxone® in aqueous solution under mild conditions at room temperature. The thus obtained 2-iodosobenzoic acids (IBAs) could be used as precursors of other cyclic organoiodine(III) derivatives by the solvolytic derivatization of the hydroxy group under mild conditions of 80 °C or lower temperature. These sequential procedures are highly reliable to selectively afford cyclic hypervalent iodine compounds in excellent yields without contamination by hazardous pentavalent iodine(III) compound.

Density functional theory (DFT) at the SMD/M06-2X/def2-TZVP//SMD/M06-2X/LANL2DZ(d),6-31G(d) level was used to explore the regioselective double oxidation of phenols by a hypervalent iodine(v) reagent (IBX) to give o-quinones.
