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

Chem Commun (Camb) 2022; 58:10985-10988.

Abstract
A radical addition/cyclization reaction of o-isocyanodiaryl amines has been developed for the efficient synthesis of potentially bioactive dibenzo[b,e][1,4]diazepine-11-carboxylates and dibenzo[b,e][1,4]diazepine-11-carboxamides. This Fe(acac)2/TBHP-promoted radical cascade process involves an unexplored isocyanide addition and the following cyclization to form 11-functionalized dibenzodiazepines. Moreover, the alkoxycarbonylation and carboxamidation of o-isocyanodiaryl amines show broad substrate scope and good functional group compatibility under mild conditions.
