Kinetics of the liquid phase selective hydrogenation of 2,3-butanedione over new composite supported Pd catalysts
(John Wiley & Sons Ltd, 2013-05)
BACKGROUND: Heterogeneous hydrogenation catalysts for fine chemical synthesis are a convenient alternative to homogeneous catalysts because of the ease of separation and reuse. In order to be good catalysts they must have ...
Estudos proteômicos e metabolômicos em animais frente à exposição à 2,3-butanodiona
(Universidade Federal de São Paulo (UNIFESP), 2016-10-31)
The 2,3-butanedione is widely used as flavoring in the food industry and in the electronic cigarette industry, but is also produced by the organisms through the oxidation of sugars, proteins and lipids. Exposure to ...
Evidence of essential arginyl residues in rabbit muscle pyruvate kinase
(1979)
Rabbit muscle pyruvate kinase is inactivated by 2,3-butanedione in borate buffer. The inactivation follows pseudo-first-order kinetics with a calculated second-order rate constant of 4.6 m-1 min-1. The modification can be ...
2,3-butanedione monoxime affects cystic fibrosis transmembrane conductance regulator channel function through phosphorylation-dependent and phosphorylation-independent mechanisms: The role of bilayer material properties
(AMER SOC PHARMACOLOGY EXPERIMENTAL THERAPEUTICS, 2006-12)
2,3-Butanedione monoxime (BDM) is widely believed to act as a chemical phosphatase. We therefore examined the effects of BDM on the cystic fibrosis transmembrane regulator ( CFTR) Cl- channel, which is regulated by ...
ENANTIOSELECTIVE HYDROGENATION OF DIKETONES ON PT SUPPORTED CATALYSTS
(TAYLOR & FRANCIS, 2005)
Enantioselective hydrogenation of 2,3-butanedione and 3,4-hexanedione has been studied over different type of supported Pt catalysts (Pt/Al2O3+, Pt/SiO2, Pt/MCM-4l) in the presence of cinchonidine (CD). Kinetic resultas ...
DNA binding, cleavage, apoptosis and cytotoxicity studies of three heteroleptic nickel complexes bearing beta-diketones
(Elsevier B.V., 2020-10-01)
In this work, three nickel(II) complexes, namely, [Ni(eta(2)-NO3)(bta)(phen)] (I), [Ni(eta(2)-NO3)(btc)(phen)] (II), and [Ni(eta(2)-NO3)(btf)(phen)] (III) (bta = 4,4,4-trifluoro-1-phenyl-1,3-butanedione anion, btc = ...
Complexes of platinum and palladium with beta-diketones and DMSO: Synthesis, characterization, molecular modeling, and biological studies
(Elsevier B.V., 2014-10-05)
This work reports on the synthesis and characterization of new complexes of the type MCl(L)DMSO], where L = 4,4,4-trifluoro-1-phenyl-1,3-butanedione (HTPB) or 4,4,4-trifluoro-1-(2-thienyl)-1,3-butanedione (HTTA) and M = ...
