1. Spectroscopic Characterization of Charge Transfer Complexes of TCNE with Aromatic Amines - The First Step of Tricyanovinylation Reaction
The first step of electrophilic aromatic substitution reactions generally involves the formation of charge transfer complexes. Tetracyanoethylene (TCNE) in the presence of aromatic amines forms π-type complexes that subsequently lead to tricyanovinylation reaction. Although this kind of reaction was investigated in the past, the spectroscopic characterizati

2. SÃntese e caracterizaÃÃo de complexos bipiridÃnicos de rutÃnio com ligantes polinitrilados / Synthesis and characterization of complexes bipiridÃnicos of ruthenium with metalto-ligand
In this work, the [Ru(bpy)(dcbpy)(TCNQ)Cl] and [Ru(bpy)(dcbpy)(TCNE)Cl] complexes, called Ru-TCNQ and Ru-TCNE, respectively, where bpy = 2,2â- bipyridine and dcbpy = 4,4â-dicarboxy-2,2â-bipyridine, were synthesized and characterized by spectroscopy and electrochemical techniques. The absorption spectra of the Ru-TCNQ and Ru-TCNE complexes showed bands ass

4. Estudo de complexos de ferro-cyclam com ligantes carboxilados e polinitrilados / Study of complexes of iron-cyclam with carboxylate ligants and polinitrilate
The main objective of this work is to contribute with the chemistry of the system Fe-Cyclam through the synthesis and characterization of complexes with carboxylate ligants, acetate and oxalate, and polinitrilate ligands, 7,7,8,8-tetracyanoquinodimethane (TCNQ) and tetracyanoethylene (TCNE). The infrared spectra of the cis-[Fe(cyclam)ox]PF6 complex allowed t
