• Mineral salts pyridine broth is a selective medium for bacteria that can metabolize pyridine (which is an unusual carbon source that a select few types of bacteria can use).
• The compound 3,6-di-2-pyridyl-1,2,4,5-tetrazine' has two pyridine substituents and is of importance as a reagent in Diels-Alder reactions.
• As pyridine is often used as an organic base in chemical reactions, pyridinium salts are produced in many acid-base reactions.
• Chemically it is based on a pyridine ring structure, with hydroxyl, methyl, aminomethyl, and hydroxymethyl substituents.
• Triclopyr (3,5,6-trichloro-2-pyridinyloxyacetic acid) is an organic compound in the pyridine group that is used as a systemic foliar herbicide and fungicide.
• Thiaminase I has the ability to use a multitude of C-N cleaving nucleophilic substrates like cysteine, pyridine, aniline, veratrylamine, dithiothreitol, and quinoline.
• Phosphorine (IUPAC name: phosphinine) is a heavier element analog of pyridine, containing a phosphorus atom instead of an aza- moiety.
• Later he made important contributions to the knowledge of dehydroacetic acid (then called dehydracetic acid), describing a number of very remarkable 'condensations,' whereby it is converted into pyridine, orcinol and naphthalene derivatives.
• 6-membered aromatic rings with one carbon replaced by another group: silabenzene, germabenzene, stannabenzene, pyridine, phosphorine, arsabenzene, stibabenzene, bismabenzene, pyrylium, thiopyrylium, selenopyrylium, telluropyrylium.
• borabenzene, silabenzene, germabenzene, stannabenzene, pyridine, phosphorine, arsabenzene, bismabenzene, pyrylium, thiopyrylium, selenopyrylium, telluropyrylium.
• Isoquinoline and quinoline are benzopyridines, which are composed of a benzene ring fused to a pyridine ring.
• Simple monocyclic aromatic rings are usually five-membered rings like pyrrole or six-membered rings like pyridine.
• For example, ring-opening metathesis polymerization using third-generation Grubbs catalyst exhibits zero order behavior in catalyst due to the reversible inhibition that occurs between pyridine and the ruthenium center.
• The Doebner modification of the Knoevenagel condensation entails the use of pyridine as a solvent with at least one of the withdrawing groups on the nucleophile is a carboxylic acid, for example, with malonic acid.
• Results confirm that cyanides are much weaker salts in pyridine than are iodides, although cyanogen iodide solutions are able to be dissolved in pyridine giving solutions with electrical conductivity that increases over time and results in maximum values.
• When the methyl groups are replaced by carboxylic acids or pyridine amide groups a host–guest chemistry interaction can take place between the Tröger's base and other molecules including glycosaminoglycans.
• In the last step of the catalytic cycle the auxiliary base (usually triethylamine or pyridine) deprotonates the protonated DMAP, reforming the catalyst.
• TFE forms complexes with Lewis bases such as THF or pyridine through hydrogen bonding, yielding 1:1 adducts.
• The original synthesis started by Eglinton reaction of di-alkyne 1,5-hexadiyne with copper(II) acetate in pyridine to give the trimer, followed by deprotonation and isomerization with potassium tert-butoxide in tert-butanol and was concluded with hydrogen organic reduction with Lindlar catalyst.
• A number of other methods exist, including the Knoevenagel condensation of acetaldehyde with malonic acid in pyridine:.
