Phenol (also known as carbolic acid, phenolic acid, or benzenol) is an aromatic organic compound with the molecular formula C6H5OH. [ 5 ] It is a white crystalline solid that is volatile. The molecule consists of a phenyl group (−C6H5) bonded to a hydroxy group (−OH).
Infobox references. Sodium phenoxide (sodium phenolate) is an organic compound with the formula NaOC 6 H 5. It is a white crystalline solid. Its anion, phenoxide, also known as phenolate, is the conjugate base of phenol. It is used as a precursor to many other organic compounds, such as aryl ethers.
The Kolbe–Schmitt reaction or Kolbe process (named after Hermann Kolbe and Rudolf Schmitt) is a carboxylation chemical reaction that proceeds by treating phenol with sodium hydroxide to form sodium phenoxide, [1] then heating sodium phenoxide with carbon dioxide under pressure (100 atm, 125 °C), then treating the product with sulfuric acid.
Phenol esters are active esters, being prone to hydrolysis. Phenols are reactive species toward oxidation . Oxidative cleavage, for instance cleavage of 1,2-dihydroxybenzene to the monomethylester of 2,4 hexadienedioic acid with oxygen, copper chloride in pyridine [ 4 ] Oxidative de-aromatization to quinones also known as the Teuber reaction .
Thiophenol is an organosulfur compound with the formula C 6 H 5 SH, sometimes abbreviated as PhSH. This foul-smelling colorless liquid is the simplest aromatic thiol.The chemical structures of thiophenol and its derivatives are analogous to phenols, where the oxygen atom in the hydroxyl group (-OH) bonded to the aromatic ring in phenol is replaced by a sulfur atom.
haloform-reaction. RSC ontology ID. RXNO:0000689. In chemistry, the haloform reaction (also referred to as the Lieben haloform reaction) is a chemical reaction in which a haloform (CHX3, where X is a halogen) is produced by the exhaustive halogenation of an acetyl group (R−C (=O)CH3, where R can be either a hydrogen atom, an alkyl or an aryl ...
The Bargellini reaction is a chemical reaction discovered in 1906 by Italian chemist Guido Bargellini. [1] The original reaction was a mixture of the reagents phenol, chloroform, and acetone in the presence of a sodium hydroxide solution. [2] Prior to Bargellini's research, the product attributed to this multi-component reaction (MCR) had been ...
The mechanism of the Reimer-Tiemann reaction. Chloroform (1) is deprotonated by a strong base (normally hydroxide) to form the chloroform carbanion (2) which will quickly alpha-eliminate to give dichlorocarbene (3); this is the principal reactive species.
