Synthesis of two new Mo(II) organometallic catalysts immobilized on POSS for application in olefin oxidation reactions
(2017-01-01)
The purpose of this work was the preparation and characterization of two new catalysts POSS-ATZAc-[Mo(η3-C3H5)Br(CO)2] (POSS-Mo-I) and POSS-ATZAc-[Mo(CO)3Br2] (POSS-Mo-II). The new heterogeneous catalysts were characterized ...
Catalytic Efficacy of Copper(II)– and Cobalt(III)–Schiff Base Complexes in Alkene Epoxidation
(Chemical Soc Japan, 2014-04)
A potentially hexadentate N2O4 donor Schiff base ligand N,N¤ -bis(5-bromo-3-methoxysalicylideneimino)-1,3- diaminopropane (H2L1 ) has been used to synthesize two mononuclear coordination complexes [Cu(L1 )]¢H2O (1) and ...

Effect of the synthetic method on the catalytic activity of alumina: Epoxidation of cyclohexene
(Facultad de Ciencias NaturalesBiologíaDepartamento de Ciencias Biológicas, 2015-02-01)
Al2O3 was prepared from different inorganic precursors via the Pechini method and compared with Al2O3 prepared by the sol–gel method. Structural characterization of these materials was carried out by FTIR, X-ray diffraction ...
