Piperidine is an organic compound with the molecular formula (CH2)5NH. This heterocyclic amine consists of a six-membered ring containing five methylene bridges (–CH2–) and one amine bridge (–NH–). It is a colorless liquid with an odor described as objectionable, and typical of amines. The name … Visa mer Piperidine was first reported in 1850 by the Scottish chemist Thomas Anderson and again, independently, in 1852 by the French chemist Auguste Cahours, who named it. Both of them obtained piperidine by reacting Visa mer Piperidine prefers a chair conformation, similar to cyclohexane. Unlike cyclohexane, piperidine has two distinguishable chair conformations: one … Visa mer • C NMR: (CDCl3, ppm) 47, 27.2, 25.2 • H NMR: (CDCl3, ppm) 2.79, 2.19, 1.51 Visa mer Piperidine is used as a solvent and as a base. The same is true for certain derivatives: N-formylpiperidine is a polar aprotic solvent with better hydrocarbon solubility than other … Visa mer Piperidine itself has been obtained from black pepper, from Psilocaulon absimile (Aizoaceae), and in Petrosimonia monandra.
