1,1′-Alkylene bis-pyridinium compounds as pickling inhibitors

Corrosion Science, 1990
The inhibition efficiencies of 1,1′-alkylene bis-pyridinium compounds have been studied for corrosion of mild steel in 0.5 M H2SO4. Substitution in the pyridine ring (R = CH3, COOH etc.) has a pronounced effect on the inhibition efficiency, though the length of the alkyl chain bound to the quaternary nitrogen atom is markedly reduced.

Quasielastic neutron scattering study of pyridinium cation reorientation in thiourea pyridinium nitrate inclusion compound

The Journal of Chemical Physics, 2008
The dynamics of the pyridinium cation in thiourea pyridinium nitrate inclusion compound has been studied using quasielastic neutron scattering in a wide temperature range (10–350K). The elastic incoherent structure factor was determined from neutron backscattering and time-of-flight measurements and its analysis allows to describe in detail the ...

Oxidation of Active Methylene Compounds by Pyridinium Chlorochromate

Synthetic Communications, 1988
Abstract 1-Aryl-1,2-diketones 6 have been obtained by pyridinium chlorochromate oxidation of benzylketones 5. In the same way 2-buten-1, 4-olide 2 and 3H-benzofuran-2-one 4 have been obtained.

Antiradiation Compounds XIII: 1-(Dithioacetic Acid)-Pyridinium Betaines

Journal of Pharmaceutical Sciences, 1970
Active mono-S-alkyl esters prepared from 1-(dithio-acetic acid)-pyridinium betaine (III) were found to be sufficiently stable for screening as radiation-protective agents, and e-withdrawing substituents in the pyridine ring gave stable betaines. Reaction of the methyl ester of III with phenacyl bromide and alkali resulted in S-alkylation to give a ...
