Aldehyde structure. In organic chemistry, an aldehyde (/ ˈ æ l d ɪ h aɪ d /) is an organic compound containing a functional group with the structure R−CH=O. [1] The functional group itself (without the "R" side chain) can be referred to as an aldehyde but can also be classified as a formyl group. Aldehydes are a common motif in many ...
This unsaturated aldehyde is then partially hydrogenated to form 2-ethylhexanal, a precursor to plasticizers such as bis(2-ethylhexyl) phthalate. [ 4 ] Butyraldehyde is a component in the two-step synthesis of trimethylolpropane , which is used for the production of alkyd resins .
It is an aldehyde, isomeric with n-butyraldehyde (butanal). [1] Isobutyraldehyde is made, often as a side-product, by the hydroformylation of propene. Its odour is described as that of wet cereal or straw. It undergoes the Cannizzaro reaction even though it has alpha hydrogen atom. It is a colorless volatile liquid.
In monometallic complexes, aldehydes and ketones can bind to metals in either of two modes, η 1-O-bonded and η 2-C,O-bonded. These bonding modes are sometimes referred to sigma- and pi-bonded. These forms may sometimes interconvert. The sigma bonding mode is more common for higher valence, Lewis-acidic metal centers (e.g., Zn 2+). [1]
Structures and distribution of glycolaldehyde as a 20% solution in water. Notice that the free aldehyde is a minor component. In acidic or basic solution, the compound undergoes reversible tautomerization to form 1,2-dihydroxyethene. [5] It is the only possible diose, a 2-carbon monosaccharide, although a diose is not strictly a saccharide.
Pivaldehyde is an organic compound, more specifically an aldehyde.Shown in the image is a line-angle representation of this organic aldehyde, whose systematic name, 2,2-dimethylpropanal, is based on the longest carbon chain (three carbon atoms), ending in "-al" to indicate the aldehyde functionality, and where another descriptive synonym is trimethylacetaldehyde. [2]
Crotonaldehyde is a chemical compound with the formula CH 3 CH=CHCHO. The compound is usually sold as a mixture of the E- and Z-isomers, which differ with respect to the relative position of the methyl and formyl groups.
At room temperature, acetaldehyde (H 3 CC(O)H) is more stable than vinyl alcohol (H 2 C=CHOH) by 42.7 kJ/mol. [3] Vinyl alcohol gas isomerizes to the aldehyde with a half-life of 30 min at room temperature. [1] H 2 C=CHOH → H 3 CC(O)H The industrial synthesis of acetaldehyde (Wacker process) proceeds via the intermediacy of a vinyl alcohol ...
