Uses

Used in Pharmaceutical Industry:
6-Methylpyridine-2-carbonitrile is used as an intermediate in the preparation of selective cyclooxygenase-2 (COX-2) inhibitors. These inhibitors are important in the development of anti-inflammatory and pain-relieving drugs, as they help reduce inflammation and pain without causing the side effects associated with non-selective COX inhibitors.
6-Methylpyridine-2-carbonitrile is also used as an intermediate in the synthesis of calcium antagonists. Calcium antagonists are a class of drugs that block the movement of calcium ions across cell membranes, which can help in the treatment of various cardiovascular diseases, such as hypertension, angina, and arrhythmias.
Used in Chemical Research and Development:
6-Methyl-2-pyridinecarbonitrile was used in the synthesis of zinc complexes bearing N,N′-bidentate entiopure ligands. These complexes have potential applications in various fields, including catalysis, coordination chemistry, and materials science. The development of novel zinc complexes can lead to advancements in these areas and contribute to the creation of new technologies and products.

Enantioselective Ni-Catalyzed Electrochemical Synthesis of Biaryl Atropisomers

A scalable enantioselective nickel-catalyzed electrochemical reductive homocoupling of aryl bromides has been developed, affording enantioenriched axially chiral biaryls in good yield under mild conditions using electricity as a reductant in an undivided cell. Common metal reductants such as Mn or Zn powder resulted in significantly lower yields in the absence of electric current under otherwise identical conditions, underscoring the enhanced reactivity provided by the combination of transition metal catalysis and electrochemistry.

Method for preparing aryl primary amide by adopting metal-catalyzed one-pot method

The invention discloses a method for synthesizing aryl primary amide by adopting a metal-catalyzed one-pot method. The method comprises the steps of: taking aryl bromidess as raw materials, allowing the aryl bromidess to react with a cyanide source under the action of a palladium catalyst, substituting bromine on an aromatic ring with cyano to obtain cyano aromatic hydrocarbon, directly adding anaqueous solution of alkali into the reaction solution without aftertreatment, and carrying out hydrolysis reaction to obtain aryl primary amide. Compared with the prior art, the method for preparing aryl primary amide from the aryl bromides has the advantages of the short synthesis route, fewer reaction steps, simple operation, mild conditions, the high conversion rate, low toxicity and industrialproduction potential.

Nanocrystalline CeO2 as a Highly Active and Selective Catalyst for the Dehydration of Aldoximes to Nitriles and One-Pot Synthesis of Amides and Esters

The dehydration of aldoximes into nitriles has been performed in the presence of various metal oxides with different acid-base properties (Al2O3, TiO2, CeO2, MgO). The results showed that a nanocrystalline CeO2 was the most active catalyst. An in situ IR spectroscopy study supports a polar elimination mechanism in the dehydration of aldoxime on metal oxide catalysts, in which Lewis acid sites and basic sites are involved. The Lewis acid sites intervene in the adsorption of the oxime on the catalyst surface while surface base sites are responsible for the C1-H bond cleavage. Thus, the acid-base properties of nanocrystalline CeO2 are responsible for the high catalytic activity and selectivity. A variety of aldoximes including alkyl and cycloalkyl aldoximes have been dehydrated into the corresponding nitriles in good yields (80-97%) using nanosized ceria which moreover resulted in a stable and reusable catalyst. Additionally, it has been showed that a variety of pharmacologically important products such as picolinamide and picolinic acid alkyl ester derivatives can be obtained in good yields from 2-pyridinaldoxime in a one-pot process using the nanoceria as catalyst.
