New route to synthesize benzothiazines
A large number of common chemical products such as medicinal drugs are based on heterocyclic organic compounds. In this work we describe a simple method for the preparation of benzothiazines, heterocycles having a bicyclic core. The method uses the commercial 2-iodoaniline as the starting...
Organisation of polyfluorinated platinum nanoparticles
Metal nanoparticles are of great interest because of their size at nanometer scale which provides them with new properties, different from those of bulk metal. In this work some materials formed by small platinum nanoparticles...
New recoverable metathesis catalysts
The preparation of several organic-inorganic hybrid materials by sol-gel process derived from Hoveyda-type monomers is described. One of them presents a nitro group at the para position with respect to the alkoxy moiety. These materials were treated with Grubbs catalysts to generate the...
New study of the coordination of pyrazole ligands to Pt(II)
Using several analytical and spectroscopic technologies, the structure of diverse complexes of Pt(II) with pyrazole ligands has been determined. The results of these structural analyses have been obtained from a series of NMR studies of
Characterization of two new ligands and their reactivity towards Rh (I)
Ligands are either atoms, ions, or molecules that bond to a central metal, generally involving formal donation of one or more of its electrons. In this research, scientists have synthesized and characterized two new ligands N-pirazole and...
Study of highly efficient molecules to improve organic synthesis
Based on a combined experimental and computacional study, authors of this work analized the effectiveness of some groups of molecules derivated from pirazol, used as precatalists in organic synthesis developed by Heck reactions.
How did heavy metal get to the road?
Roadside sediments, in which high amounts of sediments have been detected, are an environmental concern of great interest due to the possible transmission of their pollutants from traffic activities and road maintenance to humans and environment. This work analyzes leaching tests applied to...
