(Spectroscopy Soc Canada, OttawaOttawaCanadá, 2002)
Principal component analysis in studies of substituent-induced carbon-13 chemical shifts of halogenated aliphatic compounds
(Elsevier Science BvAmsterdamHolanda, 2004)
alpha-Substituent effects on C-13 NMR chemical shifts in some aliphatic compounds: Application of principal component analysis (PCA)

On the stability of the RuCl2(triphenylphosphine)(2)(amine) complexes: Ligand substituent effects of cyclic and acyclic amines
(Elsevier B.V., 2014-10-15)
In this investigation we applied the Density Functional Theory to understand the substituent effects of cyclic and acyclic amines on the stability of RuCl2(PPh3)(2)(amine) complexes. In order to evaluate the relative ...
Metal-mediated radical perfluoroalkylation of organic compounds
(Elsevier Science, 2013-11)
The incorporation of fluoroalkyl groups, and particularly the trifluoromethyl group, in pharmaceutical molecules has a profound impact on their physical and biological properties, mainly because of the unique metabolic ...
THE CATHODIC CLEAVAGE OF THE NITROBENZENESULFONYL GROUP FROM ALIPHATIC-AMINES IN N,N-DIMETHYLFORMAMIDE
(Elsevier B.V., 1991-08-26)
The reduction of benzenesulfonyl derivatives of n-butylamine and N,N-di-n-butylamine with nitro substituents at the 2, 3 and 4 positions of the phenyl ring in N,N-dimethylformamide is reported. The N,N-di-n-butyl-4- and ...
Bioreduction of beta-carboline imines to amines employing Saccharomyces bayanus
(PERGAMON-ELSEVIER SCIENCE LTD, 2010)
beta-Carboline imine reductions mediated by Saccharomyces bayanus have been described achieving moderate to good enantiomeric excesses of the amine products. The enantiomeric excesses of the bioreduction showed a dependence ...
Multi-method Study on Aquatic Humic Substances from the Rio Negro - Amazonas State/Brazil: Emphasis on Molecular-Size Classification of their Metal Contents
