This review summarizes industrial applications of inorganic and organic polyvalent (hypervalent) iodine compounds. Inorganic iodate salts have found some application as a dietary supplements food additives. Iodine pentafluoride is used fluorinating reagent, pentoxide powerful selective oxidant that particularly useful in analytical chemistry. Common hypervalent reagents such (dichloroiodo)benze...

The trans influence of various X ligands in hypervalent iodine(III) complexes of the type CF(3)[I(X)Cl] has been quantified using the trans I-Cl bond length (d(X)), the electron density ρ(r) at the (3, -1) bond critical point of the trans I-Cl bond, and topological features of the molecular electrostatic potential (MESP). The MESP minimum at the Cl lone pair region (V(min)) is a sensitive measu...

This chapter describes recent developments in stereoselective synthesis using hypervalent iodine reagents.

A novel and efficient transformation of primary alcohols to one-carbon shorter carboxylic acids using IBX is reported. Mechanistic studies revealed that the combination of IBX and molecular iodine produces a different active hypervalent iodine species.

Treatment of various aliphatic and aromatic aldoximes with the hypervalent iodine(iii) reagents (diacetoxyiodo)benzene (DIB) or Koser's reagent [hydroxy(tosyloxy)iodo]benzene (HTIB) gave, respectively, N-acetoxy or N-hydroxy amides in good yields rather than the expected nitrile oxide dimerised product oxadiazole-N-oxides reported to be formed with other oxidising and hypervalent iodine reagent...

Efficient asymmetric synthesis of spiro-2(3H)-furanones was achieved via phase-transfer-catalyzed highly enantioselective alkynylation of cyclic β-keto esters with hypervalent iodine reagents.

A direct transformation of N-aryl formamides to the corresponding carbamates via the formation of isocyanate intermediates is achieved in good yields using hypervalent iodine as an oxidant.

An oxidative amination of allenes using a single hypervalent iodine reagent is reported. The reaction proceeds very efficiently for monosubstituted allenes and leads to formation of the corresponding propargylic amines, either as the internal or as the terminal amine. The respective reaction outcome could be influenced in favor of the former product by addition of triphenylphosphine oxide to th...
