Síntese de derivados de dihidronafto[c]furanos e fenantrenos via processo de carbociclização intramolecular
(Universidade Federal de Santa Maria, 2016-11-25)
n this work, we reported the study developed for the preparation of substituted
dihydronaphtho[c]furans and phenanthrenes via intramolecular cyclization process. Firstly, a
variety of dihydronaphtho[c]furans 2 was prepared ...
Síntese de derivados de benzo[b]furanos via dupla ciclização intramolecular promovida por t-BuOK
(Universidade Federal de Santa Maria, 2016-09-23)
In this work, we reported the developed study for the preparation of substituted benzo[b]furans
via double anionic intramolecular cyclization process promoted by t-BuOK. Firstly, a variety
of 5H-benzo[d]benzofuro[3, ...
5-Aril-isoxazóis – síntese e aplicação como modelos para estudos supramoleculares
(Universidade Federal de Santa Maria, 2014-08-04)
This work describes the synthesis and halogenation of isoxazoles, and its
application as a model for investigating complexities in the self-organization of
molecules at the supramolecular level, demonstrating that the ...
Determinação de elementos-traço em borracha natural e de silicone por espectrometria de absorção atômica com forno de grafite com amostragem de sólidos
(Universidade Federal de Santa Maria, 2012-03-11)
In this work the use of solid sampling graphite furnace atomic absorption
spectrometry for the determination of Cr, Cu, Mn, Ni, Pb, Sb, Sn and Zn in
natural rubber and Cr in silicone rubber was proposed. Calibration was ...
Contaminantes metálicos em contrastes a base de quelatos de gadolínio e reações de transmetalação
(Universidade Federal de Santa Maria, 2013-10-18)
Gadolinium (Gd) is the basis of contrast media most used in magnetic resonance imaging (MRI). Because it is a very toxic metal ion, all Gd-based contrast media present chelating agents in their composition. Gd-based ...
Síntese e caracterização de triazenos e complexos com Hg(II) incluindo arranjos supramoleculares
(Universidade Federal de Santa Maria, 2011-10-14)
This work presents the synthesis of new compounds and their triazenes complexes of
mercury(II). Triazenes have three nitrogen atoms connected in sequence [ N=N N(H) ] and, when
deprotonated, they become good Lewis bases ...

(Universidade Federal de Santa Maria, 2012-08-24)
This work presents the synthesis of compounds and their triazenes complexes of gold(I), silver(I), platinum(II) and paladium(II). Triazenes have three nitrogen atoms connected in sequence [ N=N N(H) ] and, when deprotonated, ...
Triazenos N-óxidos e seus complexos de Au(I) e Pd(II): uma abordagem no contexto da engenharia de cristais
(Universidade Federal de Santa Maria, 2018-02-02)
This work presents the synthesis of several molecular models, divided into four
chapters, and which were strategically synthesized for application in Crystal Engineering. In
the first chapter the synthesis of a series ...
Mono-, bis- e tris-triazenos, tetrazeno e complexos de Cu(I), Ag(I), Au(I), Cu(II), Ni(II), Pd(II) E Cu(III): síntese, caracterização, estrutura cristalina, atividades antitumoral, antibacteriana e de clivagem do DNA in vitro
(Universidade Federal de Santa Maria, 2013-01-31)
Multi-nitrogenated ligands are versatile coordinating ligands to the transition metals. In this
work, mono- and bis-triazenes, a tris-triazene, a tetrazenide and twelve metal complexes were
synthesized, including the ...
