Photoredox Synthesis of Aryl-Hydroxylamines from Carboxylic Acids and Nitrosoarenes [PDF]
Hydroxylamines are found in biologically active compounds and serve as building blocks for the preparation of nitrogen-containing molecules. Here, we demonstrate the direct conversion of carboxylic acids into the corresponding alkyl hydroxylamines using ...

Tetramethylarsenverbindungen mit kovalenter Molekülstruktur
The preparation and the properties of tetramethyl arsenic derivatives of some hydroxylamines [HONH2, HONHCH3, HON(CH3)2] and oximes [HON=CHCH3, HON=C(CH3)2] are described. The IR-, Raman- and 1H-NMR-spcctra of these monomeric compounds prove a non-ionic

Palladium-Catalyzed Alkenyl C–H Activation/Diamination toward Tetrahydrocarbazole and Analogs Using Hydroxylamines as Single-Nitrogen Sources [PDF]
A palladium-catalyzed alkenyl C–H activation/diamination reaction of cycloalkenyl bromoarenes with hydroxylamines is described. A wide range of tetrahydrocarbazoles and analogs has been prepared using fine-tuning bifunctional secondary hydroxylamines as ...

Oxidative fragmentation of tertiary cyclopropanols with phenyliodine(III) dicarboxylates in aprotic solvents (dichloromethane, chloroform, toluene) produces mixed anhydrides. The fragmentation reaction is especially facile with phenyliodine(III) reagents

RuO4-mediated oxidation of secondary amines: Part 1. Are hydroxylamines main intermediates? [PDF]
The RuO4-catalyzed oxidation of secondary amines Bn-NH-CH2R (1a-b; R=H, Me) gave mainly amides, but minute amounts of nitrones PhCH=N(O)-CH2R (9a-b) and traces of Bn-N(OH)-CH2R (R=H, 4a) were also detected.

Synthesis of N,N,O‑Trisubstituted Hydroxylamines by Stepwise Reduction and Substitution of O‑Acyl N,N‑Disubstituted Hydroxylamines [PDF]
Diverse N,N,O-trisubstituted hydroxylamines, an under-represented group in compound collections, are readily prepared by partial reduction of N-acyloxy secondary amines with diisobutylaluminum hydride followed by acetylation and reduction of the so ...

Catalyst-Free Direct Olefin Halo-Hydroxylamination: Rapid Syn-thesis of Multifunctional Hydroxylamines (MFHAs) for Structurally Complex Amines and N-Heterocycles [PDF]
Herein, we introduce a novel and powerful alkene difunctionalization process where anomeric amides (e.g., N-halogenated O-activated hydroxylamines) react directly with olefins, without the use of catalysts or additives, to yield the corresponding N ...

Para-Substituted O-Benzyl Sulfohydroxamic Acid Derivatives as Redox-Triggered Nitroxyl (HNO) Sources
Nitroxyl shows a unique biological profile compared to the gasotransmitters nitric oxide and hydrogen sulfide. Nitroxyl reacts with thiols as an electrophile, and this redox chemistry mediates much of its biological chemistry.
