The chemistry of hypervalent iodine compounds has been experiencing considerable attention of organic chemists during the past few years. Hypervalent iodine reagents have found ubiquitous applications in organic synthesis because of their mild and highly chemoselective oxidizing properties, easy commercial availability, and environmental benign character. Along with oxidation of alcohol, they have also shown to be useful in number of organic transformations which include oxidative functionalization of carbonyl compounds, catalytic imidations, cyclization, oxidative coupling of phenols, amines and related compounds. Among various hypervalent iodine reagents, iodine-V compounds (λ5-iodanes) have attracted much attention in recent years. This review narrates the particular advances in iodine (V) reagents with special emphasis on the use of DMP in organic transformations.

The elimination of volatile organic solvents in organic synthesis is the most important goal in “Green” chemistry. We report a simple, efficient and facile method for the addition of progargyl bromide to carbonyl compounds using Mg metal as a mediator under solvent-free conditions which could regioselectively generate homopropargyl alcohols efficiently in good to excellent yields. The procedure has advantages such as short reaction time, operationally simple, excellent product yields, high regioselectivity and organic solvent-free.

Chiral hypervalent iodine reagents are active players in modern stereoselective organic synthesis. Structurally diverse chiral hypervalent iodine reagents have been synthesised and extensively studied, but hypervalent iodine reagents containing chiral sulfur stereogenic centre are scarce and their synthesis is challenging. A small library of iodoarenes containing chiral sulfinamide and chiral sulfoximine moieties has been synthesised using commercially available reagents. The oxidation of the chiral iodoarene precursors to iodine(III) reagents was cumbersome due to facile overoxidation of the sulfoxide moiety and hence loss of chirality under various oxidation conditions. Oxidation of chiral sulfonimidoyl derivatives to the corresponding hypervalent iodine reagents was successful and led to novel sulfur-based chiral iodine(III) reagents.

An efficient, eco-friendly protocol for selective oxidation of primary and secondary Baylis–Hillman alcohols to the corresponding carbonyl compounds in high yields has been developed with 2-iodosobenzoic acid (IBA).
