- Carbonyl compounds are molecules
containing the carbonyl group, C=O. These include aldehydes and
ketones.
- Common names are also used for
carbonyl-containing substituent groups,which are known collectively as
acyl groups.
- The acidity of β-dicarbonyl
compounds is considerably higher than that of monocarbonyl compounds and
other dicarbonyl compounds.
- In keto-enol equilibrium of
β-dicarbonyl compounds, the (mono)enolic form usually exceeds the keto
form.
- A β-dicarbonyl compound's enol is
additionally stabilized through resonance of the enol's carbon-carbon
double bond with the second carbonyl group, the enol's hydroxy hydrogen
is, on the other hand, connected to the carbonyl oxygen by a hydrogen
bridge bond.
- A reaction did take place,
however, when a b-lactone and a cyclic 2-diazo-1,3-dicarbonyl
compound were stirred in the presence of rhodium acetate, the
product unexpectedly being the dioxepinone.
- The difference in O/N-selectivity
observed between the L-proline- and L-prolinamide-catalyzed reaction is
thought to result from activation of the oxygen through protonation of
the nitrogen of nitrosobenzene by the carboxylic acid function of
L-proline.
- The catalytic, enantioselective
amination of α-cyanoacetates and β-dicarbonyl compounds with
β-isocupreidine to form tetrasubstituted stereocenters.
- Employing inexpensive
N-chlorosuccinimide as the electrophilic chlorine source and a
diphenylpyrrolidine catalyst, Jørgensen reports high yields (90-99%) and
good enantioselectivities with a variety of aldehydes.
