Nitrones and oxaziridines. VIII. Cycloaddition reactions of nitrones with isothiocyanates
Australian Journal of Chemistry, 1973Whereas nitrones undergo cycloaddition to the C=N double bond of phenyl isothiocyanate, predominant addition to the C=S double bond of substituted phenyl isothiocyanates, methyl isothiocyanate and benzoyl isothiocyanate occurs. However, these cycloadducts are not stable but undergo fragmentation usually with the formation of thioamides and isocyanates.

Studies on the chemistry of the chiral nitronic acid and nitronic esters
Tetrahedron: Asymmetry, 1997Abstract Some new chemistry of the chiral nitronic acid and nitronic esters is described. Conversions with retention of configuration are found among the chiral nitronic acid, oxime, nitronic esters and O -alkyloximes. α,β-Elimination reactions of nitronic esters are observed for the first time. Novel and enantiopure chiral bisheterocyclic compounds

C−H Reactivity of the α‐Position in Nitrones and Nitronates
Advanced Synthesis & Catalysis, 2019AbstractThe review summarizes the chemistry of nitrones and nitronates in the context of the C−H reactivity of their α‐carbon atoms. Electrophilic, nucleophilic and radical reactions leading to functionalization of the α‐position are described. Examples of the application of these processes in total synthesis are outlined.magnified image

Alloy Digest, 1981
Abstract Nitronic 20 was designed for elevated-temperature use where high mechanical strength and resistance to oxidation and sulfidation are important. This stainless steel exhibits high mechanical strength throughout the 1000-1700 F (538-927 C) temperature range, yet it is malleable at forging temperatures and provides excellent hot ...
