Benzylideneacetone is the organic compound described by the formula C 6 H 5 CH=CHC(O)CH 3. Although both cis- and trans-isomers are possible for the α,β-unsaturated ketone, only the trans isomer is observed. Its original preparation demonstrated the scope of condensation reactions to construct new, complex organic compounds. [1]
Benzylidene acetal of glucose.. Benzylidene compounds are, formally speaking, derivatives of benzylidene, although few are prepared from the carbene.Benzylidene acetal is a protecting group in synthetic organic chemistry of the form PhCH(OR) 2.
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.
(Benzylideneacetone)iron tricarbonyl is the organoiron compound with the formula (C 6 H 5 CH=CHC(O)CH 3)Fe(CO) 3. It is a reagent for transferring the Fe(CO) 3 unit. [ 1 ] This red-colored compound is commonly abbreviated (bda)Fe(CO) 3 .
(Benzylideneacetone)iron tricarbonyl is an organoiron compound with an η 2 ketone ligand. Some η 2-aldehyde complexes insert alkenes to give five-membered metallacycles. [5] η 1-Complexes of alpha-beta unsaturated carbonyls exhibit enhanced reactivity toward dienes. This interaction is the basis of Lewis-acid catalyzed Diels-Alder reactions.
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.
Some derivatives derivatives are prepared displacement of bda from (benzylideneacetone)iron tricarbonyl (Fe(bda)(CO) 3) [12] The Fe(CO) 3 unit serves as a protecting group for the diene, preventing the diene from participating in Diels-Alder reactions and hydrogenation. The diene is usually deprotected with ceric ammonium nitrate. [13]
Benzylacetone (IUPAC name: 4-phenylbutan-2-one) is a liquid with a sweet, flowery smell that is considered to be the most abundant attractant compound in flowers (e.g. Coyote Tobacco, Nicotiana attenuata) [1] [2] and one of volatile components of cocoa.
