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.

Excited-state dynamics of thiophene substituted betaine pyridinium compounds

Phys. Chem. Chem. Phys., 2014
This work deals with the photophysics of novel pyridinium betaine based on 2-pyridin-1-yl-1H-benzimidazole (SBPa) substituted symmetrically by mono- (Th2SBPa) and bi-thiophene fragments (Th4SBPa). The study is based on a combination of steady-state, femtosecond transient absorption spectroscopic measurements supported by PCM-(TD)DFT calculations. It is
