It is the conjugate acid of pyridine. Many related cations are known involving substituted pyridines, e.g. picolines, lutidines, collidines. They are prepared by treating pyridine with acids. [3] As pyridine is often used as an organic base in chemical reactions, pyridinium salts are produced in many acid-base reactions.
Profenofos can be synthesized by reacting phosphorus oxychloride with sodium ethoxide and sodium 1-propanethiolate, followed by treatment with 4-bromo-2-chlorophenol. [ 6 ] : 332 Toxicity
In organic synthesis, PPTS is used as a weakly acidic catalyst, providing an organic soluble source of pyridinium (C 5 H 5 NH +) ions.For example, PPTS is used to deprotect silyl ethers or tetrahydropyranyl ethers when a substrate is unstable to stronger acid catalysts.
MPP + (1-methyl-4-phenylpyridinium) is a positively charged organic molecule with the chemical formula C 12 H 12 N +. It is a monoaminergic neurotoxin that acts by interfering with oxidative phosphorylation in mitochondria by inhibiting complex I , leading to the depletion of ATP and eventual cell death .
Phenol (also known as carbolic acid, phenolic acid, or benzenol) is an aromatic organic compound with the molecular formula C 6 H 5 OH. [5] It is a white crystalline solid that is volatile. The molecule consists of a phenyl group (−C 6 H 5) bonded to a hydroxy group (−OH). Mildly acidic, it requires careful handling because it can cause ...
For example, reduction with lithium aluminium hydride yields a mixture of 1,4-dihydropyridine, 1,2-dihydropyridine, and 2,5-dihydropyridine. [102] Selective synthesis of 1,4-dihydropyridine is achieved in the presence of organometallic complexes of magnesium and zinc , [ 103 ] and (Δ3,4)-tetrahydropyridine is obtained by electrochemical ...
N-Isopropyl-N′-phenyl-1,4-phenylenediamine (often abbreviated IPPD) is an organic compound commonly used as an antiozonant in rubbers. [1] Like other p-phenylenediamine -based antiozonants it works by virtue of its low ionization energy , which allows it to react with ozone faster than ozone will react with rubber. [ 2 ]
4-Dimethylaminopyridine (DMAP) is a derivative of pyridine with the chemical formula (CH 3) 2 NC 5 H 4 N. This white solid is of interest because it is more basic than pyridine , owing to the resonance stabilisation from the NMe 2 substituent.
