8.2 Combination with Potentially Polymerizable Group with an Appropriate Partner Groups that belong to this category are typically those with condensation polymerization mechanism. They include aldehyde, azide, carboxylic acid, hydroxy ethylether, isocyanate, methylol, and phenol. A benzene ring provides re...
o‐Benzene-dicarb-aldehyde (systematic name: benzene‐1,2‐dicarb-aldehyde), C8H6O2, exhibits a weak intramolecular hydrogen bond between an aldehyde H atom and the O atom of the adjacent aldehyde group, with a C?O distance of 2.852?(2)??. m‐Benzene-dicarb-aldehyde (systematic name:...
Benzene is a widely used commodity chemical, which is currently produced from fossil resources. Lignin, a waste from lignocellulosic biomass industry, is the most abundant renewable source of benzene ring in nature. Efficient production of benzene from lignin, which requires total transformation of Cs...
in concentrated alkali solution (Conicaro reaction, Cannizarro reaction): one molecule of aldehyde is reduced to the corresponding alcohol, and the other molecule of aldehyde is oxidized to carboxylate at the same time. The speed of this reaction depends on the substituents on the aromatic ring....
Benzofuran is a molecule that combines a benzene ring with one or more connected heterocyclic furan rings.
When more than one substituent is attached to a benzene ring, the substituents are numbered so as to give the lowest numbers possible to the substituents. In derivatives with accepted trivial names (such as styrene) the carbon including the functional group inherent to the derivative is assigned ...
1,3,5-Tris(4-formyl-3-hydroxyphenyl)benzene (CAS number 2244985-34-8) is composed of three salicylaldehydes attached to a benzene ring. The salicylaldehyde, also known as 2-hydroxybenzaldehyde, readily undergoes reactions with amine and hydrazine derivatives, resulting in the formation of a ...

ring. Each carbon was bound once to one adjacent carbon and twice to the carbon on its other side. And each used its fourth bond to hold a hydrogen atom outside the ring. Modern chemistry owes much of its power to the understanding of ringed carbon compounds that started with Kekulé's ...
1. 1,4-benzoquinone compounds or pharmaceutically acceptable salts thereof of the formula ##STR54## wherein R1 is a lower alkyl group, a lower alkoxy group, an amino group, a hydroxyl group or a lower alkanoyloxy group; R2 is a hydrogen atom, a halogen atom, a lower alkyl group, a ...
