Synthesis and Crystal Structure of Bis pyridinium 1,2-Ethane periodate
In the title salt, [C12H14N2]2+, 2[IO4]–, the cation is organized around an inversion center located at the centre of the
CH2CH2 moiety and the two pyridine moieties are placed in anti positions with respect to each other. The I atom is in...

THEORETICAL STUDY ON THE MOLECULAR TAUTOMERISM OF THE 5-HYDROXY-2-HYDROXY METHYL PYRIDINE-4(1H)-ONE
5-hydroxy-2-hydroxy methyl pyridine- 4(1H)-one is one of the Hydroxypyridin-4(1H)-one
derivatives which are known in coordination as efficient metal ions chelators. In this work, relative
stabilities of 5-hydroxy-2-hydroxy methyl...
PROTON TUNNELING IN PYRIDINE-PYRIDININIUM AND ITS 2-AMINO AND 2-AMINO-4-METHYL DERIVATIVES COMPLEXES
Pyridine and its derivatives have attracted a lot of attention owing to their applications in many areas of chemistry. In particular, they have been used very frequently as proton acceptors in studies involving hydrogen-bonded complexes [1...

NORMAL COORDINATE ANALYSIS AND VIBRATIONAL ASSIGNMENTS FOR PYRIDINE AND ITS DEUTERATED DERIVATIVES
Pyridine and its derivative compounds have been extensively studied from the spectroscopic point of view, mainly due to its presence in many chemicals of high interest in a variety of biomedical and industrial fields. The vibrational spectra...
Diastereoselective synthesis of highly functionalized quinolizines via a pyridine-based three-component reaction and a DFT investigation on the reaction mechanism
Novel, one-pot, three-component reactions of the zwitterions generated in situ from pyridine and acety-
lenic esters with alkoxymethylenemalononitriles via 1,4-dipolar cycloadditions are described. The reac-
tions afforded dialkyl 1...
A facile and diastereoselective access to functionalised benzopyrano[3,4-a] quinolizines via a pyridine-based three-component reaction
The reaction of 2-oxo-2H-chromene-3-carbonitriles with dialkyl acetylenedicarboxylates and pyridines results in a three-component
condensation reaction in which the 2-oxo-2H-chromene-3-carbonitrile group acts as a dipolarophile to produce...
TiO 2 ‐nanoparticles as efficient catalysts for the synthesis of pyridine dicarbonitriles
The catalytic effects of two forms of nano-TiO2, which are prepared via an ordinary
or a magnetized process, are investigated in the synthesis of pyridine
dicarbonitriles by one-pot multicomponent reaction of 4-methyl thiophenol...
