A team of the lasir co-author of an article in the Angewandte Chemie

September 2016

An unpublished process and of the most interesting for the synthesis chemistry was highlighted thanks to the collaborative work of our team in EPR (réseau Renard) and researchers of the Parisian Institute of Molecular in the UPMC.

Of biomimetic inspiration, the organometallic complex carrying redox ligands know a greater catalytic development. Their trademark is the relocation on the ligand of the electronic transfers usually centered on the metal. A new reactivity was recently observed on a copper complex carrying totally oxidized non-innocent redox ligands. It was shown that the oxidized character of ligands conferred on the metallic center a character of high masked valence allowing the complex to form a C-N bond, this is an interesting process for the chemistry of synthesis and unpublished work in this context.

This work, fruit of a collaboration between the Parisian Institute of Molecular Chemistry the UPMC and the laboratory LASIR of Lille, was possible thanks to advanced EPR studies in particular thanks to network Renard. These results were the object of an article appeared in the review Angewandte Chemie.
