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 ...
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...

General procedure of the synthesis of benzenesulfonyl hydrazones is based typically on the condensation reaction of hydrazide of substituted benzenesulfonic acid with appropriate aldehyde or ketone (Scheme 1.). Ethanol, methanol, buthanol or tetrahydofurane are used as typical solvents during the react...
There are two types of Friedel-Crafts reactions, alkylation and acylation. Alkylation reaction add a simple carbon chain to the benzene ring.Acylation adds an acyl group, creating a ketone or aldehyde. How is benzene converted to benzaldehyde?
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....
5-bromovanillin component of BNV is a phenolic aldehyde with the aldehyde, hydroxyl, and ether functional group. Considering the structure of BNV different points where it can interact with 1018CS can be established. The free electron pairs on N and O, and the π-electrons from the aromatic ...

Subsequently, oxidation to benzaldehyde and then to benzoic acid is carried out by the alcohol and aldehyde dehydrogenase, respectively. All populations appear to have two forms of aldehyde dehydrogenase, one having a high Km and one with a much lower Km. However, some Japanese and possibly ...
Ein anderer Syntheseweg ist beispielsweise die Umsetzung der metallorganischen Verbindungen mit Aldehyden, nachfolgender Dehydratisierung und abschließender Reduktion der entstandenen Doppelbindung. Verbindungen der Formel I, in denen Z1 -CH=CH- oder -C≡C-bedeutet, können auf dem oben...
