Pyridinium Salts of Dehydrated Lanthanide Polychlorides
Molecules, 2022 The reaction of lanthanide (Ln) chloride hydrates ([Ln(H2O)n(Cl)3]) with pyridine (py) yielded a set of dehydrated pyridinium (py-H) Ln-polychloride salts. These species were crystallographically characterized as [[py-H-py][py-H]2[LnCl6]] (Ln-6; Ln = La, Ce, Pr, Nd, Sm, Eu, Gd) or [[py-H]2[LnCl5(py)]] ((Ln-5; Ln = Tb, Dy, Ho, Er, Tm, Yb, Lu).

On the photochemical reaction of pyridinium salts with nucleophiles [PDF]
Photochemical & Photobiological Sciences, 2021 AbstractDFT calculations on the photochemical reaction of 1-n–N-butylpyridinium salt in water with hydroxide anion is in agreement with a singlet state process where the S2 state at λ = 253 nm can be converted into a Dewar isomer (2-butyl-2-azabicyclo[2.2.0]hexa-2,5-dien-2-yl cation).

Quaternary Pyridinium Salts: A Review
Journal of Oleo Science, 2008 Cationic surfactants are being used in various applications industrially and domestically for a long time. Pyridinium salts come under the category of cationic surfactants. These are unsaturated heterocyclic compounds having different functional groups present either on pyridine ring or at nitrogen atom.
