Louis Fensterbank. Louis Fensterbank is a French scientist specialized in molecular chemistry. Professor at Sorbonne University and Senior Member of Institut Universitaire de France, he has been the director of the Institut Parisien de Chimie Moléculaire since 2017.

Biography 

In 1990, Fensterbank graduated as chemical engineer from Ecole Supérieure de Chimie Industrielle de Lyon, now École Supérieure de Chimie Physique Électronique de Lyon. He obtained his PhD in 1993 at the State University of New York at Stony Brook under the guidance of Scott Sieburth. Following a lecturer position at the Pierre and Marie Curie University (UPMC), he was appointed in 1995 by the French National Centre for Scientific Research as a chargé de recherche with Max Malacria. In 2004, he became professor at UPMC, now Sorbonne Université.

Research 

Louis Fensterbank's research objectives deal with the invention of synthetic methods by means of three interconnected themes: radical chemistry, organometallic catalysis and organosilicon chemistry. He developed original radical processes using new partners that lead to complex molecular systems. In the context of a "greener" radical chemistry, new radical promotors have been invented. These studies have also stimulated the development of new redox systems based on the oxidation of anions (enolates, trifluoroborates and silicates). Photoredox versions of these processes have been devised.

His contribution in organometallic catalysis has focused on the electrophilic activation of π-systems by gold or platinum complexes, which allows expedient access to polycyclic systems from polyunsaturated substrates and can be applied to the total synthesis of complex terpenes. Mechanistic studies, as well as the development of enantioselective versions of these reactions have accompanied these works. His group is now involved in the photoactivation of gold-catalyzed processes, notably via photosensitization

His third active field of investigation concerns the development of organosilicon Lewis acids and their use in synthesis or as precursors of hypercoordinated silicon species of interest. 

He is co-author of more than 250 publications and book chapters.

Awards 

In 2008, Louis Fensterbank was nominated junior member of Institut Universitaire de France, of which he became a senior member in 2021. He was awarded the Clavel Lespiau Prize of the French Academy of Sciences in 2014, the Prize of the Division de Chimie Organique of the Société chimique de France in 2016, and the Silver Medal of the French National Centre for Scientific Research in 2017. He has been a fellow of the Royal Society of Chemistry since 2017.

Fensterbank was a visiting scientist at the Australian National University in 2009 and invited professor at the Osaka Prefecture University in 2017 and at Okayama University in 2019.

Radesca S.A.. Radesca S.A. (also known as JUAN J. RADESCA S.A.) is an electronics manufacturing company in Uruguay, in the neighborhood of Peñarol in Montevideo. The company is the only producer of lead-acid batteries in the country.  The factory was founded in 1935 and has been operated as a family business since. As of 2013, they employed 43 people and were protected by the national government as part of maintenance of national industries, especially for national automotive parts. They gained significant prominence during the Import substitution industrialization policy period during the 1960s.

Their main manufacturing and smelting plant for lead in Montevideo is one of the main sources of lead contamination in the country. During the 1960s, the plant employed a number of processes for lead-acid battery recycling that exposed both employees and the local communities to large levels of industrial contamination. Workers would later describe active collusion between doctors, state agencies and the managers to hide the impact of lead on worker health.
