Abstract:
We report the synthesis of novel N-coordinated λ5-iodanes as a unique class of hypervalent iodine compounds. X-ray diffraction analysis revealed their intriguing (pseudo)cyclic structure, showcasing distinctive N⋯I-secondary bonding interactions. We demonstrate the in situ generation of reactive diacetoxy derivatives, which exhibits remarkable efficacy in alcohol oxidation reactions. Thermal stability assessments using TGA/DSC analysis provide crucial insights into the handling and potential applications of these compounds. This work expands the frontier of hypervalent iodine chemistry, offering new tools for selective oxidation reactions.

Alkynes to Aldehydes and Ketones: Hydroboration-Oxidation
One of the convenient methods for the preparation of aldehydes and ketones is via hydration of alkynes. Hydroboration-oxidation of alkynes is an indirect hydration reaction in which an alkyne is treated with borane followed by oxidation with alkaline peroxide to form an enol that rapidly converts into an aldehyde or a ketone. Terminal alkynes form aldehydes, whereas internal alkynes give ketones as the final product.
