Solvents inducing oxidation of hydroxylamines.
Hydroxylamines gradually undergo oxidation to their oximes on being dissolved in organic solvent (e.g. methanol). This phenomenon was followed by (1)H-NMR and liquid chromatography-mass spectrometry (LC-MS). The oxidation rate was estimated from the peak area observed on the mass chromatogram at the protonated molecule or fragment ion on LC-atmospheric pressure chemical ionization (APCI)-MS. Th...
متن کاملSupramolecular structures of three isomeric 2-chloro-N-(nitrophenyl)nicotinamides.
Molecules of 2-chloro-N-(2-nitrophenyl)nicotinamide, C12H8ClN3O3, are linked by two C-H...O hydrogen bonds into a chain of edge-fused R(2)(2) (14) and (4)(4) (24) rings. In 2-chloro-N-(3-nitrophenyl)nicotinamide monohydrate, C12H8ClN3O3.H2O, the molecules are linked by a combination of N-H...O, O-H...O and O-H...N hydrogen bonds into a chain of edge-fused rings containing two distinct types of ...
متن کاملIsomeric N-(iodophenyl)nitrobenzamides form different three-dimensional framework structures.
The isomeric N-(iodophenyl)nitrobenzamides, C(13)H(9)IN(2)O(3), all form different three-dimensional framework structures. Molecules of N-(2-iodophenyl)-3-nitrobenzamide (II) are linked by a combination of N-H...O and C-H...O hydrogen bonds and a two-centre iodo...carbonyl interaction. The supramolecular structure of N-(2-iodophenyl)-4-nitrobenzamide (III) is built from one N-H...O and two C-H....
متن کاملPlant cells oxidize hydroxylamines to NO
Plants are known to produce NO via the reduction of nitrite. Oxidative NO production in plants has been considered only with respect to a nitric oxide synthase (NOS). Here it is shown that tobacco cell suspensions emitted NO when hydroxylamine (HA) or salicylhydroxamate (SHAM), a frequently used AOX inhibitor, was added. N(G)-hydroxy-L-arginine, a putative intermediate in the NOS-reaction, gave...
