Few functional groups are as popular in synthesis as the carbonyl group. Composed of an oxygen molecule doubly bonded to carbon, the carbonyl welcomes reaction with all types of nucleophiles ...

Aldehydes with heteroaromatic substituents (that is, furyl, ... Duthaler, R. O. & Hafner, A. Chiral titanium complexes for enantioselective addition of nucleophiles to carbonyl groups.

Aldehydes, ketones and carboxylic acids are the compounds containing carbon-oxygen double bond (>C=O) called carbonyl group. The carbon and oxygen of the carbonyl group are sp 2 hybridised and the ...

Figure 1 Example of a cyclisation reaction with D-glucose. When an aldose cyclizes, the hydroxyl group on C5 undergoes an intramolecular reaction with the C1 carbonyl group of the aldehyde. The ...

Nucleophilic addition of enolate anion to the carbonyl group (R = H, alkyl, phenyl) In the next step ß-hydroxy aldehyde or ketone is formed by reaction with water, and the reaction is completed by ...

Answer: (i) The carbonyl group of aldehydes and ketones is reduced to the CH 2 group on treatment with zinc amalgam and concentrated hydrochloric acid. (ii) Aldehydes which do not have an α ...

This is called a carbonyl group. Imine Formation. ... yielding the corresponding amine and carbonyl containing compound (aldehyde or ketone). In this process, the imine undergoes an addition of water.

Scientists at Scripps Research have used rapid alternating current (AC) to selectively reduce carbonyl groups (J. Am. Chem. Soc. 2021, DOI: 10.1021/jacs.1c06572).

Aldehydes and ketones are compounds with carbonyl groups that play an important role in our foods. Oxidation of food.
