Cooperative effects of H+ and H- hydrido carbonyl ruthenium derivatives; role of homogeneous and heterogeneous protonic and lewis acids in catalytic hydrocarbonylation reactions
(Elsevier B.V., 1989-11-01)
The role played by H+ hydrido iodocarbonyl and H- hydrido carbonyl ruthenium catalysts in the different catalytic steps of hydroformylation and hydroesterification of olefins, and in the homologation of alcohols has been ...
Low cost selective sensor for carbonyl compounds in air based on a novel conductive poly(p-xylylene) derivative
(ELSEVIER SCIENCE BV, 2009)
A novel poly(p-xylylene), PPX, derivative bearing phenyl side groups was electrochemically synthesized in 85% yield. The polymer, poly(2-phenyl-p-xylylene) (PPPX), presented a major fraction (88%) soluble in common organic ...
Theoretical study of photochemical hydrogen abstraction by triplet aliphatic carbonyls by using density functional theory

Predicting the reaction mechanism of nucleophilic substitutions at carbonyl and thiocarbonyl centres of esters and thioesters
(2012)
In nucleophilic substitution reactions at carbonyl centres, there are two possible channels. The first one occurs when the attack of nucleophilic agents takes place simultaneously with the departure of the nucleofuge. This ...
Predicting the reaction mechanism of nucleophilic substitutions at carbonyl and thiocarbonyl centres of esters and thioesters
(John Wiley & Sons, 2012)
In nucleophilic substitution reactions at carbonyl centres, there are two possible channels. The first one occurs when the attack of nucleophilic agents takes place simultaneously with the departure of the nucleofuge. This ...
Synthesis and characterization of polynuclear complexes of molybdenum carbonyl derivatives with pyridine-2-carbaldehyde azine (pa) and ferrocenylphosphines. Crystal structure of [Mo2(CO)6(μ-dppf)(μ-pa)] (dppf = 1,1′-bis(diphenylphosphino)ferrocene)
(Elsevier Ltd, 1998)
Novel mono- and didentate ferrocenylphosphines containing complexes, [Mo2(CO)6(dfpp)2(μ-pa)] (dfpp = diferrocenylphenylphosphine) and [Mo2(CO)6(μ-dppf)(μ-pa)], have been isolated and characterized by infrared and electronic ...
Compostos β-enamino carbonílicos: obtenção utilizando microondas, avaliação da sua reatividade e atividade antimicrobiana
(Universidade Federal de Santa MariaBRQuímicaUFSMPrograma de Pós-Graduação em Química, 2007-05-10)
In this work, we explored new methodologies to obtain β-enamino carbonylic compounds derived from 1,3-dicarbonyl and α-amino acids using microwave and solvent
free conditions. The β-enamino carbonylic compounds were ...
