The Azidofunctionalization of Alkenes
ChemistryEurope, EarlyView.The azidofunctionalization of alkenes offers a powerful strategy for synthesizing nitrogen‐containing compounds by installing both an azide and a second functional group in one step. This approach, employing photoredox catalysis, transition metals, and radical methods, is efficient, selective, and versatile, with applications in pharmaceuticals and ...

Metal-free synthesis of indanes by iodine(III)-mediated ring contraction of 1, 2-dihydronaphthalenes [PDF]
, 2011 A metal-free protocol was developed to synthesize indanes by ring contraction of 1, 2-dihydronaphthalenes promoted by PhI(OH)OTs (HTIB or Koser's reagent).

In Situ Generation of Alkyl–λ3–Iodanes as Soft and Highly Reactive Electrophiles
ChemistryEurope, EarlyView.A convenient and practical method for the clean generation of alkyl–λ3–iodanes is reported using tetraalkylsilanes and iodine tris(trifluoroacetate). An in situ‐generated methyl–λ3–iodane works as a soft and highly electrophilic methylation reagent, which enables methylation of tertiary sulfonamides at low temperatures and following transamidation and ...

The chemical bond as an emergent phenomenon
, 2017 We first argue that the covalent bond and the various closed-shell interactions can be thought of as symmetry broken versions of one and the same interaction, viz., the multi-center bond.

The Versatility of Diazirines: Properties, Synthetic and Modern Applications
Chemistry – A European Journal, EarlyView.Diazirines are 3‐membered heterocycles containing two nitrogen atoms connected by a double bond. They possess a multi‐faceted reactivity that holds great potential for organic synthesis. This review discusses their properties, modes of activation, and their many modern uses, underlining their underappreciated versatility: as carbene precursors, but ...

OH-Radical Oxidation of Lung Surfactant Protein B on Aqueous Surfaces [PDF]
, 2018 Air pollutants generate reactive oxygen species on lung surfaces. Here we report how hydroxyl radicals (·OH) injected on the surface of water react with SP-B_(1–25), a 25-residue polypeptide surrogate of human lung surfactant protein B.

Platform Design Enabling Silver(III) Stabilization ─ The Uprise of AgIIICF3 Chemistry?
Chemistry – A European Journal, EarlyView.Oxidation state +III represents the highest known for silver compounds. This Concept Article critically analyzes the main strategies allowing for the authentication of silver(III) compounds, with special focus on AgIIICF3 species, that were discovered back in the 80′s and 90′s, but brought back to the scene very recently. They often display an inverted

Chemistry–Methods, EarlyView.An efficient mechanochemical route for diphenyleneiodonium (DPI) salt synthesis is reported which offers a sustainable and solvent‐free alternative. The solid‐state reactivities of the reported DPI salts were also assessed with the help of morphology predictions and Hirshfeld surface analysis computations to understand the effect of crystal morphology,
