Piperdine

Molfile expand, piperdine. A molecular entity having an available pair of electrons capable of forming a covalent bond with a piperdine Br o nsted base or with the vacant orbital of some other molecular entity Lewis base, piperdine. A substance that increases the rate of piperdine reaction without modifying the overall standard Gibbs energy change in the reaction. A molecular entity capable of accepting a hydron from a piperdine Br o nsted acid.

Piperidine is an organic compound with the molecular formula CH 2 5 NH. This heterocyclic amine consists of a six-membered ring containing five methylene bridges —CH 2 — and one amine bridge —NH—. It is a colorless liquid with an odor described as objectionable, typical of amines. Piperidine was first reported in by the Scottish chemist Thomas Anderson and again, independently, in by the French chemist Auguste Cahours , who named it. Industrially, piperidine is produced by the hydrogenation of pyridine , usually over a molybdenum disulfide catalyst: [12].

Piperidines are among the most important synthetic fragments for designing drugs and play a significant role in the pharmaceutical industry. Their derivatives are present in more than twenty classes of pharmaceuticals, as well as alkaloids. The current review summarizes recent scientific literature on intra- and intermolecular reactions leading to the formation of various piperidine derivatives: substituted piperidines, spiropiperidines, condensed piperidines, and piperidinones.

Explore the properties, synthesis, uses, and safety measures of Piperidine, a crucial compound in pharmaceuticals and agrochemicals. Piperidine is a versatile organic compound that plays an integral role in numerous chemical reactions and industrial processes. It is an organic compound classified under the family of heterocyclic amines. Its structural configuration is a six-membered ring with five carbon atoms and one nitrogen atom, often symbolized as CH 2 5 NH. Piperidine is a clear, colorless liquid that has a characteristic odor. It is miscible with water and many organic solvents, indicating its highly polar nature. When it comes to its chemical properties, Piperidine serves as a base in many reactions, and its nucleophilic character makes it an essential ingredient in various synthetic processes. The primary production of Piperidine involves the reaction of pentanenitrile with hydrogen in a process known as catalytic hydrogenation. This reaction yields piperidine and ammonia as the main products.

The same is true for certain derivatives: N -formylpiperidine is a polar aprotic solvent with better hydrocarbon solubility than other amide solvents, and 2,2,6,6-tetramethylpiperidine is a highly sterically hindered base, useful because of its low nucleophilicity and high solubility in organic solvents. These include piperine , which gives black pepper its spicy taste. Privacy Notice and Terms of Use.
