Investigation of Methyl Pyridinium-2-aldoxime Salts

Journal of Pharmaceutical Sciences, 1961
Methyl pyridinium-2-aldoxime iodide (2-PAM iodide) has been reported to be effective in preventing and overcoming the toxic effects in animals poisoned with organic phosphorus compounds that are inhibitors of the cholinesterase enzymes. In order to obtain greater water solubility of the oxime and to eliminate undesirable side effects due to the iodide ...

Iridium‐Catalyzed Asymmetric Hydrogenation of Pyridinium Salts

Angewandte Chemie International Edition, 2012
As one of the most straightforward and powerful approaches for the preparation of optically active compounds, asymmetric hydrogenation has been successfully used for different types of aromatic compounds, including quinolines, isoquinolines, quinoxalines, indoles, pyrroles, furans, imidazoles, and aromatic carbocyclic ring, with excellent ...

Oxidation of reduced triphosphopyridine nucleotide by pyridinium salts

Archives of Biochemistry and Biophysics, 1967
Abstract Certain substituted pyridinium salts are able to support oxidation of TPNH. Ferredoxin, ferredoxin-TPN reductase, and molecular oxygen are necessary. water rather than Peroxide is formed, as shown by the stoichiometry of the reaction. During the Reaction the pyridinium salts do not undergo Spectral changes.

Syntheses Using Pyridinium Salts

Angewandte Chemie International Edition in English, 1963
AbstractThis review discusses syntheses leading to a new type of N‐vinylpyridinium salts, to novel anionocyanines, to aminophenazines and alloxazines, as well as to (aza‐) dehydroquinolizinium, acridizinium, and morphanthridizinium salts. In addition, Mannich reactions and aminoalkylations at active methylene groups of cycloimmonium salts, and their ...
