Hypervalent Iodine(III)‐Catalyzed Balz–Schiemann,

An unprecedented hypervalent iodine(III) catalyzed Balz–Schiemann reaction is described. In the presence of a hypervalent iodine compound, the fluorination reaction proceeds under mild conditions (25–60 °C), and features a wide substrate scope and good functional‐group compatibility.Hypervalent Iodine Compounds - Organic Chemistry,Hypervalent Iodine Compounds. Weaker and longer than covalent linkages, hypervalent bonds are the result of a linear three-center, four-electron (3c-4e) electronic distribution (hypervalent model). Hypervalent iodine reagents are useful synthetic tools due to their low toxicity, ready availability, and ease of handling.Hypervalent Iodine - Oxidizing Agents | Sigma-Aldrich,Hypervalent Iodine.

Continuous‐Flow Electrochemical Generator of Hypervalent,

Unstable hypervalent iodine reagents can be prepared easily and coupled with different substrates to achieve oxidative transformations in high yields. The unstable, electrochemically generated reagents can also easily be transformed into classic bench‐stable hypervalent iodineHypervalent Iodine(III) Compounds as Biaxial Halogen Bond,,“Hypervalent” iodine(III) derivatives have been established as powerful reagents in organic transformations, but so far only a handful of studies have addressed their potential use as halogen-bonding noncovalent Lewis acids. In contrast to “classical” halogen-bond donors based on iodine(I) compounds, iodine(III) salts feature two directional electrophilic axes perpendicular to each,Hypervalent Iodine - Oxidizing Agents | Sigma-Aldrich,Hypervalent Iodine.
