Usage

Ketone

A ketone is a type of organic compound featuring a carbonyl group (C=O) bonded to two carbon atoms. 1-Penten-3-one, 4,4-dimethyl-1,1-diphenylis a ketone due to the presence of the carbonyl group in its structure.

Chemical structure

The structure of 1-Penten-3-one, 4,4-dimethyl-1,1-diphenylincludes two phenyl groups (aromatic rings) and a pentenone functional group (a carbon-carbon double bond with a酮羰基 (C=O) at the third carbon position).

Pentenone functional group

A pentenone is a type of ketone with a carbon-carbon double bond (C=C) and a carbonyl group (C=O) in its structure. In 1-Penten-3-one, 4,4-dimethyl-1,1-diphenyl-, the pentenone group contributes to its unique chemical properties and reactivity.

Metal- and Acid-Free Methyl Triflate Catalyzed Meyer-Schuster Rearrangement

A novel metal- and acid-free preparation of synthetically useful α,β-unsaturated carbonyl compounds from propargyl alcohols has been realized. This Meyer-Schuster rearrangement process is effectively catalyzed by methyl triflate (20 mol%) to prepare a broad scope of conjugated E -enals and E -enones generally in good to excellent yields (up to 90%). This reaction procedure operates under mild conditions (70 °C), in air, with short reaction times (1 h). Moreover, a carbocation intermediate trapped by the solvent 2,2,2-trifluoroethanol was isolated during this transformation.

Enantioselective reduction of ketones and imines catalyzed by (CN-Box)ReV-oxo complexes

The development and application of chiral, non-racemic ReV-oxo complexes to the enantioselective reduction of prochiral ketones is described. In addition to the enantioselective reduction of prochiral ketones, we report the application of these complexes to 1) a tandem Meyer-Schuster rearrangement/reduction to access enantioenriched allylic alcohols and 2) the enantioselective reduction of imines.

Synthese de β-imidazolylcetones

The synthesis of β-imidazolylketones 1 and 2 is described.The compounds 1 are prepared by reaction of Mannich bases with the imidazole.Treatment of the imidazole with haloketones or α-ethylenic ketones or the reaction of β-ketol with the N,N'-thionyldiimidazole lead to β-imidazolylketones 2.
