Tetramethylarsenverbindungen mit kovalenter Molekülstruktur

CHIMIA, 1975
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

Catalytic dechlorination of diclofenac by biogenic palladium in a microbial electrolysis cell [PDF]

, 2012
Diclofenac is one of the most commonly detected pharmaceuticals in wastewater treatment plant (WWTP) effluents and the receiving water bodies. In this study, biogenic Pd nanoparticles (bio-Pd) were successfully applied in a microbial electrolysis cell ...

Generation of Mixed Anhydrides via Oxidative Fragmentation of Tertiary Cyclopropanols with Phenyliodine(III) Dicarboxylates

Molecules, 2020
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]

Journal of the Serbian Chemical Society, 2016
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.

Para-Substituted O-Benzyl Sulfohydroxamic Acid Derivatives as Redox-Triggered Nitroxyl (HNO) Sources

Molecules, 2022
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.
