2015年2月17日 · Arene — Compound which contains a benzene ring. Aromatic Compounds — Compounds having aroma (wait, the modern definition is different, I know) Every arene is an aromatic compound but every aromatic compound need not be an arene. Mathematically, $$\text{arene} \subset \text{aromatic compounds}$$

2020年4月13日 · In the above example, there is no substituents on the ring and hence the final product remains irrespective of which $\ce{C-O}$ bond in the arene oxide cleaves to open the ring. Later, the author presented the following reaction where the ring has an electron donating group - methyl group:

2012年4月26日 · When treated with hot, concentrated acidic $\\ce{KMnO4}$, arenes are oxidised to the corresponding carboxylic acids. For example, toluene is oxidised to benzoic acid. I've tried to examine how this

2015年3月17日 · Modern research has shown that the traditional organic chemisty mechanism of electrophilic aromatic substitution, in this case, is actually not true. The intermediate (sometimes call the sigma complex or the Wheland intermediate) in which SO3 is bound to the arene leaving a positive charge on the arene, actually does not exist.

2018年6月13日 · phenols: Compounds having one or more hydroxy groups attached to a benzene or other arene ring. aryl groups: Groups derived from arenes by removal of a hydrogen atom from a ring carbon atom. Glossary of Class Names of Organic Compounds and Reactive Intermediates Based on Structure. Pure App. Chem. 1995, 67, 1307

2017年6月19日 · I know that in a diazotisation reaction, the temperature should be carefully maintained within the range of 0–5 °C by use of an ice bath.

2012年7月3日 · Compounds having one or more hydroxy groups attached to a benzene or other arene ring, e.g., 2-naphthol: (source: iupac.org) A phenol consists of an - $\ce{OH}$ bonded to an unsaturated $\mathrm{sp^2}$ carbon. Thus, it does not qualify as an alcohol. One can classify it as an enol, though.

You can find the answer in: M. Randić Aromaticity of Polycyclic Conjugated Hydrocarbons Chem. Rev. 103 (2003) 3449-3605.

2018年5月14日 · You just deprotonate the amine, the hydrocarbon part of the Grignard reagent ends up an an alkane (or an arene if there are aromatic rings), then on acid workup you get just the amine (or ammonium ion) back. Yup, this is not a very productive synthesis.
