Natural sucrose esters: Perspectives on the chemical and physiological use of an under investigated chemical class of compounds
(2020-09-01)
The present review describes the chemistry and physiological properties of the sucrose esters (SEs) obtained from natural or synthetic pathways, with emphasis on those that have aliphatic and phenylpropanoid substituents ...
Design and characterization of pH-sensitive spirorhodamine 6G probes with aliphatic substituents
(Elsevier Science SA, 2019-11)
We report synthesis and photophysical studies of spirorhodamines (SRA) with amide N-aliphatic substituents, including measurements of single-crystal X-ray structures, fluorescence emission, and quantum mechanical calculations. ...
The alpha-substituent effect of alkyl groups in the C-13 NMR and IR data of some aliphatic nitriles
(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)

Substituent effects on the photolysis of methyl 2-carboxylate substituted aliphatic 2H-azirines
(Elsevier Science, 2007-05)
In this study, the UV induced photochemical reactions of two 2H-azirines – methyl 2-chloro-3-methyl-2H-azirine-2-carboxylate (MCMAC) and methyl 3-methyl-2H-azirine-2-carboxylate (MMAC) – isolated in argon matrices are ...
Substituent effects in the C-13 NMR chemical shifts of alpha-mono-substituted acetonitriles
(Pergamon-elsevier Science LtdOxfordInglaterra, 2007)
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 ...
