Synthesis and identification of nicotinium sulfate (3-(1-methylpyrrolidin-2-yl)pyridine:H 2 SO 4 ) from tobacco-extracted nicotine: A protic ionic liquid and biocompatible catalyst for selective acetylation of amines

Hydrogen bonding versus packing effects in the crystal structure of 3-((1R,2S)-1-methylpyrrolidin-1-ium-2-yl)pyridin-1-ium tetraiodidozincate(II), C10H16I4ZnN2

“…Outlook. It may be of interest to test more nicotin-1,1′dium tetrahalogenidometallate salts in catalysis as for other nicotin-1,1′-dium salts some catalytic properties are observed [24,25].…”

Efficient Synthesis of 6,7-Dihydro-5H-cyclopenta[b]pyridine-3-carbonitrile Compounds and Their Applicability As Inhibitor Films for Steel Alloy Corrosion: Collective Computational and Practical Approaches

“…Even so, most of these methodologies are subject to restrictions of the highest temperatures, the time of the reaction is very high, and the yield is very low. 21 Nowadays, to find an environmentally friendly catalyst that works in normal conditions is still a significant challenge for producing 3-cyanopyridine derivatives. The heterocyclic molecules used as corrosion inhibitors are revealed to have the most efficient corrosion inhibition.…”

Even so, most of these methodologies are subject to restrictions of the highest temperatures, the time of the reaction is very high, and the yield is very low . Nowadays, to find an environmentally friendly catalyst that works in normal conditions is still a significant challenge for producing 3-cyanopyridine derivatives.…”

Synthesis of triarylpyridines with sulfonate and sulfonamide moieties via a cooperative vinylogous anomeric-based oxidation

“…In addition to the above, pyridine derivatives perform a key role in the area of catalysis. Pyridine-based catalysts have been explored as metal complex catalysis 28 , chiral ligands for asymmetric catalysis 29 , molecular machines such as rotaxanes and catenanes [30][31][32] , organo-catalysis 33 , polymer-based catalysts 34 and ionic liquids 35 .Particularly, triarylpyridine derivatives, a notable subset of pyridine family, are emerging as an important class of heterocyclic compounds that have many biological properties that contain anti-cancer 36 , anti-depressant 3738 and anti-bacterial 38 activities. Moreover, triarylpyridines have been applied as chemosensors 39 , ligands 40 , and important intermediates for directional synthesis of insecticides, and surfactants 41 .…”
