Synthesis of Benzo-Fused Heterocycles by Intramolecular alpha-Arylation of Ketone Enolate Anions
(American Chemical Society, 2012)
Unexpected formation of 4,4-dimethyl-1,2-disubstituted-dicarbonyl cyclopentanes from ketone enolate anions and 1,3-diiodo-2,2-dimethylpropane
(Royal Society of Chemistry, 2016-03-07)
Cyclic 1,4-dicarbonyl compounds can be easily obtained by mixing a solution of aryl methyl or alkyl methyl ketone enolate anions with 1,3-diiodo-2,2-dimethylpropane in DMSO. This represents the first example of dimerization ...
Gaussian basis sets by generator coordinate Hartree-Fock method to ab initio calculations of electron affinities of enolates
(Elsevier B.V., 2002-07-05)
The Generator Coordinate Hartree-Fock (GCHF) method is employed to generate uncontracted 15s and 18s11p gaussian basis sets for the H, C and O atoms, respectively. These basis sets are then contracted to 3s and 4s H atom ...

Anions involved in the initiation of the thermally induced SRN1 reaction for α-arylation of ketones
(Royal Society of Chemistry, 2017-06)
The SRN1 reaction between acetophenone enolate and PhI is thermally induced and accelerated by microwave irradiation to give the corresponding substitution product 1,2-diphenylethanone in a 50% yield in DMSO at 70 °C. ...
An expedient route to heterocycles througha-arylation of ketones and arylamides bymicrowave induced thermal SRN1 reactions
(Royal Society of Chemistry, 2014-03)
Microwave irradiation promotes a quick aromatic nucleophilic substitution by a thermally induced electrontransfer process to form new C–C bonds by the coupling of aryl radicals and enolate nucleophiles. Diverse2-aryl-1-p ...
Microwave role in the thermally induced SRN1 reaction for a-arylation of ketones
(The Royal Society of Chemistry, 2015-02)
The coupling between iodobenzene and the enolate anion of acetophenone is accelerated by microwave irradiation. This increase in reaction rate is only ascribed to thermal effects. The coupling reaction gave the corresponding ...
Estudio computacional de alquilaciones estereoselectivas de enolatos de litio
(Universidad de los AndesQuímicaFacultad de CienciasDepartamento de Química, 2020-06-12)
La estereoselectividad es un factor crucial en la síntesis de compuestos biológicamente activos, y los auxiliares quirales desempeñan un papel fundamental en el control de esta propiedad. Se ha demostrado experimentalmente ...
Síntese da SBA-15 funcionalizada com aminossilanos e sua aplicação na condensação aldólica entre o furfural e a acetona
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Química - PPGQCâmpus São Carlos, 2021-10-14)
The petroleum is used to manufacture plastics, solvents and, mainly, to produce fuels. However, some factors such as fluctuation in the price of the barrel, its non-renewable origin and the release of greenhouse gases make ...
