Chemistry of materials in Brazil: A look through the Brazilian Chemical Society annual meetings.
(Soc Brasileira QuimicaSao PauloBrasil, 1998)
Materials chemistry in 25 years of Brazilian Chemical Society.
(Soc Brasileira QuimicaSao PauloBrasil, 2002)
Química de materiais em 25 anos de SBQ
(Sociedade Brasileira de Química, 2002-05-01)
Communications on Chemistry of Materials topics were already presented in the first annual meetings of the Brazilian Chemical Society, dispersed throughout various meeting sections. The SBQ Materials Chemistry division was ...
Ionization of the FeX bond in polar solvents: A spectroscopic study of CpFe(dppe)X complexes
(1993)
Electronic absorption spectra for complexes CpFe(dppe)X [with X = Cl, I and CN; dppe = (Ph)2PCH2CH2P(Ph)2; Cp = η5-C5H5] and the cationic derivative [CpFe(dppe)NCCH3]PF6 in different solvents have been measured. The lower ...
Coordinating properties of some solvents in Cr(CO)5L complexes
(1988)
The influence of the donor-acceptor properties of several solvents on the Cr(CO)5 group in the solid [Cr(CO)5·solvent] complexes has been examined by spectroscopic methods. Relationships were found between the acceptor ...
Sulfur(II)-metal coordination compounds. Group VI metal carbonyl complexes with N,N′-thiobisamines ligands
(1984)
The novel complexes M(CO)5S(NR2)2 (M = Cr, Mo or W) have been prepared by the addition of N,N′-thiobisamine (NR2 = dimethylamine, piperidine, morpholine or dibenzylamine) to UV-irradiated tetrahydrofuran solutions of M(CO)6. ...
Sulphurating and coordinating properties of N,N′-thiobismorpholine towards iron carbonyls
(1990)
The reactions of N,N′-thiobismorpholine, {A figure is presented}, with Fe(CO)5, Fe2(CO)9, Fe3(CO)11 and [(η5-C5H5)Fe(CO)2THF]BF4 were examined. Thiobismorpholine undergoes desulphurization towards Fe(CO)5 with formation ...
New complexes [CpFe(dppe)thiophenes]PF6
(Elsevier Ltd, 1996)
The reactions of CpFe(dppe)I with thiophenes in the presence of T1PF6 afforded the new complexes [CpFe(dppe)thiophenes]PF6 (thiophenes = thiophene, 2-methyl-thiophene, 3-methyl-thiophene, 2,5-dimethyl-thiophene, benzothiophene ...
Conformation and optical activity of copper(II) complexes with L-aminoacids in the visible region
(1976)
The Cotton effect of dd transitions of copper(II) complexes with optically active aminoacids in aqueous media is qualitatively analyzed in terms of conformational models by means of a simple one-electron MO treatment. The ...
