Dibenzylideneacetone or dibenzalacetone, often abbreviated dba, is an organic compound with the formula C 17 H 14 O. It is a pale-yellow solid insoluble in water, but soluble in ethanol. It is a pale-yellow solid insoluble in water, but soluble in ethanol.
2,2,4,4-Tetramethyl-1,3-cyclobutanediol (CBDO) is an aliphatic diol.This diol is produced as a mixture of cis- and trans-isomers, depending on the relative stereochemistry of the hydroxyl groups.
In organic chemistry, the Claisen–Schmidt condensation is the reaction between an aldehyde or ketone having an α-hydrogen with an aromatic carbonyl compound lacking an α-hydrogen.
Water clusters have been proposed as an explanation for some anomalous properties of liquid water, such as its unusual variation of density with temperature. Water clusters are also implicated in the stabilization of certain supramolecular structures. [3] They are expected to play a role also in the hydration of molecules and ions dissolved in ...
Tris(dibenzylideneacetone)dipalladium(0) or [Pd 2 (dba) 3] is an organopalladium compound.The compound is a complex of palladium(0) with dibenzylideneacetone (dba). It is a dark-purple/brown solid, which is modestly soluble in organic solvents.
The compound with the formula (C 5 H 5) 2 Fe 2 (CO) 4 exists as three isomers in solution. In one isomer the CO ligands are terminal. When a pair of CO are bridging, cis and trans isomers are possible depending on the location of the C 5 H 5 groups. [7] Another example in organometallic chemistry is the linkage isomerization of ...
As with most methyl ketones, benzylideneacetone is moderately acidic at the alpha position, and it can be readily deprotonated to form the corresponding enolate [6]. The compound undergoes the reactions expected for its collection of functional groups: e.g., the double bond adds bromine, the heterodiene adds electron-rich alkenes in Diels-Alder reactions to give dihydropyrans, the methyl group ...
This reaction is, overall, a condensation reaction as two molecules joining together with loss of water. Mechanistically, it is an example of addition-elimination reaction: nucleophilic addition of the -NH 2 group to the C=O carbonyl group, followed by the elimination of a H 2 O molecule: [3] X-ray structure of DNP-derived hydrazone of ...
