Oxaziridines: Versatile Reagents in Modern Organic Synthesis
Being capable of transferring an O atom and N‐group/atom, oxaziridines are considered multitasking agents. These are employed for diverse organic transformations, such as epoxidation of olefins, α‐ and γ‐hydroxylation/amination of carbonyl compounds, oxidation of sulfides, [3+2]cycloaddition with unsaturated systems.

Synthesis of Some Substituted 1,3,4-Oxadiazoles from Hydrazones [PDF]
In this paper the synthesis of some 2-(3-pyridyl)-5-aryl-1,3,4-oxadiazoles from hydrazones is reported. Nicotinic acid was converted to ethyl nicotinate (1) by its reaction with thionyl chloride and the resultant acid chloride was treated with absolute ...

Rapid alternating polarity (rAP) electrolysis enables the direct decarboxylative borylation of aromatic carboxylic acids under transition‐metal‐ and external‐oxidant‐free conditions. Dynamic polarity switching suppresses electrode passivation and supports efficient aryl radical generation, providing an energy‐efficient route from abundant aromatic acid
