Publikováno v: Dalton Transactions. 50:1901-1912

Oxidative C-C bond cleavage of 2-aminophenols mediated by transition metals and dioxygen is a topic of great interest. While the oxygenolytic C-C bond cleavage reaction relies on the inherent redox non-innocent property of 2-aminophenols, the metal c

Acetatos homo e heterotrinucleares de ferro: um experimento para o laboratório de química de coordenação Homo and heterotrinuclear iron acetates: an experiment for the coordination chemistry laboratory

Autor: Reginaldo da Silva Santos, Sergio Augusto Venturinelli Jannuzzi, André Luiz B. Formiga

Publikováno v: Química Nova, Vol 33, Iss 8, Pp 1815-1820 (2010)

Homo and heterotrinuclear acetates are unique compounds having μ3-oxo bridge and many interesting properties of such compounds are derived from this structure. Some undergraduate inorganic textbooks discuss several aspects of these compounds and we

Spin State Energetics and Oxyl Character of Mn-Oxo Porphyrins by Multiconfigurational ab Initio Calculations: Implications on Reactivity

Autor: Kristine Pierloot, Sergio Augusto Venturinelli Jannuzzi, André Luiz Barboza Formiga, Quan Manh Phung, Alex Domingo

Publikováno v: Inorganic Chemistry. 55:5168-5179

Important electromeric states in manganese-oxo porphyrins MnO(P)(+) and MnO(PF4)(+) (porphyrinato or meso-tetrafluoroporphyrinato) have been investigated with correlated ab initio methods (CASPT2, RASPT2), focusing on their possible role in multistat

Publikováno v: Electrochimica Acta. 113:332-339

This work describes for the first time the modification of a glassy carbon electrode with a hybrid material formed by the dispersion of multi-walled carbon nanotubes in the metallopolymer P4VP-Fe(CN)5. The reversible redox couple of the material was
