Hypervalent iodine(III) compounds have found wide application in modern organic chemistry as environmentally friendly reagents and catalysts. iodine are commonly used synthetically important halogenations, oxidations, aminations, heterocyclizations, various oxidative functionalizations of substrates. Iodonium salts arylating reagents, while iodonium ylides imides excellent carbene nitrene precursors. Various derivatives benziodoxoles, such azidobenziodoxoles, trifluoromethylbenziodoxoles, alkynylbenziodoxoles, alkenylbenziodoxoles group transfer the presence transition metal catalysts, under metal-free conditions, or using photocatalysts photoirradiation conditions. Development hypervalent catalytic systems discovery highly enantioselective reactions chiral represent a particularly recent achievement field chemistry. Chemical transformations promoted by many cases unique cannot be performed any other common, non-iodine-based reagent. This review covers literature published mainly last 7-8 years, between 2016 2024.

A benziodazole-type O2NO-I(III) compound was used as a nitrating reagent to react with series of electron-rich arenes including substituted phenols and anilines, affording the corresponding nitration products under mild conditions. Mechanistically, generates reactive nitrogen dioxide (NO2) species, which enables anilines.

Empowered by the ubiquity of carbonyl functional groups in organic compounds, decarbonylative functionalization was prevalent construction complex molecules. Under this context, asymmetric has emerged as an efficient pathway to accessing chiral motifs. However, ablation enantiomeric control a conventional 2e transition metal–catalyzed process notable because harsh conditions (high temperatures, etc.) that are usually required. To address challenge and use readily accessible aldehyde directly, we report radical azidation cyanation. Diverse aldehydes were directly used alkyl precursor, engaging subsequent inner-sphere or outer-sphere ligand transfer where motifs (CN N 3 ) could be incorporated excellent site- enantioselectivity. Mild conditions, broad scope, regioselectivity (driven polarity-matching strategy), enantioselectivity shown for both transformations. This strategy using precursor offered powerful reaction manifold transformations construct regio- stereoselectively.

Chiral propargylic cyanides are often used as small-molecule feedstocks for the introduction of chiral centers into various valuable products and complex molecules. Here, we have developed a highly atom-economical strategy copper complex-catalyzed synthesis cyanides. Propargylic radicals can be smoothly obtained by direct decarboxylation carboxylic acids without preactivation. The reactions show excellent selectivity functional group compatibility. Gram-scale reaction several conversion from cyanide demonstrated synthetic value this strategy.
