Furan is a heterocyclic organic compound, consisting of a five-membered aromatic ring with four carbon atoms and one oxygen atom. Chemical compounds containing such rings are also referred to as furans.

A current hypothesis for the mechanism of furan-induced carcinogenesis is metabolic activation of furan by cytochrome P450 to a reactive and cytotoxic intermediate that stimulates cell replication, increasing the likelihood of tumor induction.

Furan reacts with n-butyllithium in ether yields 2-furanlithium which when reacts with carbondioxide in HCl gives furan-2-carboxylic acid. Reaction of Furan with Maleic Anhydride (Diels-Alder Reaction)

Apr 27, 2016 · You can only assign hybridisation states to an atom if you already know its geometry, based on some experimental or theoretical evidence. The geometry of the oxygen in furan is trigonal planar and therefore the hybridisation must be $\ce{sp^2}$.

Sep 29, 2014 · The purpose of this article is to give a taste of just how powerful the union between furans and photochemically-generated singlet oxygen is proving to be as a synthetic tool and to suggest that this chemistry is only now really coming of age. In attempting to achieve this goal, its progress from mechanistic

Thermochemical Properties, Rotation Barriers, and Group Additivity for Unsaturated Oxygenated Hydrocarbons and Radicals Resulting from Reaction of Vinyl and Phenyl Radical Systems with O2. The Journal of Physical Chemistry A 2005 , 109 (10) , 2233-2253.

Mar 14, 2015 · Furan is aromatic because one of the lone pairs of electrons on the oxygen atom is delocalized into the ring, creating a $4n+2$ Hückel aromatic system. The steric number is sometimes incorrectly described as the sum of the number …

Nov 24, 2009 · The prospects of using the oxidation processes of furan and its homologs in the synthesis of alkoxy- and dialkoxydihydrofurans, 5-alkoxy-2(5H)-furanones, β-formylacrylic acid, maleic acid, and its dialdehyde are indicated.

furan, in contrast to its derivatives, is more selective; the yield of maleic anhydride is higher, and complete transformation of the furan is achieved in a shorter period. The photosensitized oxidation of furan and alkylfurans by molecular oxygen under various conditions

Jan 2, 2022 · Furan (C 4 H 4 O) is a heterocyclic organic compound, consisting of a five-membered aromatic ring with four carbon atoms and one oxygen. Chemical compounds containing such rings are also referred to as furans.
