Cyclopentanol or cyclopentyl alcohol is a cyclic alcohol. It is also known as hydroxycyclopentane. [2] Reactions
Phenanthrene is a polycyclic aromatic hydrocarbon (PAH) with formula C 14 H 10, consisting of three fused benzene rings. It is a colorless, crystal-like solid, but can also appear yellow. Phenanthrene is used to make dyes, plastics, pesticides, explosives, and drugs. It has also been used to make bile acids, cholesterol and steroids. [3]
A Polycyclic aromatic hydrocarbon (PAH) is a class of organic compounds that is composed of multiple aromatic rings.Most are produced by the incomplete combustion of organic matter— by engine exhaust fumes, tobacco, incinerators, in roasted meats and cereals, [1] or when biomass burns at lower temperatures as in forest fires.
As a result, while anthracene reacts with maleic acid, phenanthrene does not, and triphenylene is the most stable species of these three. [ 1 ] Three Clar structures with an increasing number of π-sextets: anthracene (on the left), phenanthrene (in the middle), and triphenylene (on the right).
Polycyclic aromatic hydrocarbons are organic compounds that contain at least three fused benzene rings.A typical polycyclic aromatic hydrocarbon is benzopyrene.. Hydrocarbons consist of only carbon and hydrogen.
Nudol is a phenanthrene from the orchids Eulophia nuda, Eria carinata and Eria stricta. [10] 9,10-Dihydro-2,5-dimethoxyphenanthrene-1,7-diol is a phenanthrene from Eulophia nuda. This compound shows cytotoxic activity against human cancer cells. [11] 2,7-Dihydroxy-3,6-dimethoxyphenanthrene is a phenanthrene from Dehaasia longipedicellata. [12]
The term alcohol originally referred to the primary alcohol ethanol (ethyl alcohol), which is used as a drug and is the main alcohol present in alcoholic drinks. The suffix -ol appears in the International Union of Pure and Applied Chemistry (IUPAC) chemical name of all substances where the hydroxyl group is the functional group with the ...
The Bogert–Cook synthesis (1933) involves the dehydration and isomerization of 1-β-phenylethylcyclohexanol to the octahydro derivative of phenanthrene [23] The Darzens–Nenitzescu synthesis of ketones (1910, 1936) involves the acylation of cyclohexene with acetyl chloride to methylcyclohexenylketone.
