Nicotinonitrile or 3-cyanopyridine is an organic compound with the formula NCC 5 H 4 N. The molecule consists of a pyridine ring with a nitrile group attached to the 3-position. A colorless solid, it is produced by ammoxidation of 3-methylpyridine: [2] H 3 CC 5 H 4 N + NH 3 + 1.5 O 2 → NCC 5 H 4 N + 3 H 2 O. Nicotinonitrile is a precursor to ...
In these conversions, chloride is displaced. [2] Pyrithione, the conjugate base of 2-mercaptopyridine-N-oxide, is a fungicide found in some shampoos. Oxidation 2-chloropyridine gives 2-chloropyridine-N-oxide. [5] The antihistamine pheniramine may be generated via the reaction of phenylacetonitrile with 2-chloropyridine in the presence of a base ...
The compound has C 2h symmetry, with each metal atom having pseudo-octahedral geometry.In the crystal structure, two isomers are observed in the unit cell, one with a 2.93 Å ruthenium–ruthenium bond and the other with a long internuclear distance of 3.75 Å.
The first step of synthesis is a condensation reaction between the molecule 2-chloro 3-cyanopyridine and the molecule 1-methyl-3-phenylpiperazine. [121] History
The Pinner reaction refers to the acid catalysed reaction of a nitrile with an alcohol to form an imino ester salt (alkyl imidate salt); this is sometimes referred to as a Pinner salt. [1] The reaction is named after Adolf Pinner , who first described it in 1877.
Pyridine-N-oxide is the heterocyclic compound with the formula C 5 H 5 NO. This colourless, hygroscopic solid is the product of the oxidation of pyridine. It was originally prepared using peroxyacids as the oxidising agent. The compound is used infrequently as an oxidizing reagent in organic synthesis. [1]
2,6-Dichloropyridine is a chloropyridine with the formula C 5 H 3 Cl 2 N. A white solid, it is one of six isomers of dichloropyridine . It serves as a precursor to the antibiotic enoxacin , [ 2 ] as well as the drug and anpirtoline and the antifungal liranaftate .
3-Chloropyridine is an aryl chloride and isomer of chloropyridine with the formula C 5 H 4 ClN. It is a colorless liquid that is mainly used as a building block in organic synthesis. [1] The compound is a substrate for many coupling processes including the Heck reaction, [2] Suzuki reaction, [3] and Ullmann reaction. [4]
