20th Molecules Webinar

σ-Hole–Based Interactions: Halogen Bonds, Chalcogen Bonds and Beyond

σ-holes are electrophilic regions observed in halogens, chalcogens and many other atoms, allowing them to interact with molecular partners bearing nucleophilic regions. The interactions based on σ-holes are becoming increasingly recognized as significant within the family of noncovalent interactions. Indeed, during the last two decades, the σ-hole-based interactions have found more and more applications in the context of supramolecular chemistry, crystal engineering and catalysis, to name a few.
This webinar, given by three experts in the field, is intended to present a short overview of the importance of σ-hole interactions in chemistry by focusing on selected recent applications.

Date: 2 November 2021

Time: 2:00pm CET | 9:00am EDT | 9:00pm CST Asia

Victor Mamane is a CNRS researcher at the University of Strasbourg. He graduated from Orsay University (near Paris) in 1998 while working under the supervision of Prof. H. B. Kagan. He obtained his Ph.D. at the same university in 2001 with Prof. O. Riant. He then moved to Germany, where he spent two years in Prof. A. Fürstner’s group in Mülheim/Ruhr and one year in Prof. H. Waldmann’s group in Dortmund. In 2004, he was awarded the position of CNRS researcher at the University of Nancy, where he developed new methodologies in heterocyclic chemistry. In 2013, he moved to the University of Strasbourg, where he started a new project dedicated to the study of -hole interactions in solution and their application in catalysis. Currently, he is a member of the Organic Section Board of Molecules.

François Gabbaï was born in 1968 in Montpellier (France). Upon completion of his undergraduate chemistry studies at the Université de Bordeaux in 1990, he joined the graduate program at the University of Texas at Austin to work with Alan Cowley. After obtaining his Ph.D. in 1994, he was awarded an Alexander von Humboldt Fellowship and subsequently a Marie Curie Fellowship, which allowed him to work with H. Schmidbaur at the Technische Universität München (Germany) as a postdoctoral fellow and later as a habilitand. In 1998, he joined Texas A&M University, where he now holds the Arthur E. Martell Chair of Chemistry. François, who is a member of the advisory board of several international journals, has served as an associate editor for Organometallics between 2011 and 2019, and for Chemical Science since April 2019. He is a Fellow of the American Chemical Society (ACS), a Fellow of the Royal Society of Chemistry, and the recipient of the 2009 North American Dalton Lectureship. In 2016, he received the F. Albert Cotton Award in Synthetic Inorganic Chemistry from the ACS. His most recent recognitions include a 2019 Distinguished Achievement Research Award from the Texas A&M Association of Former Students and his promotion to the title of Distinguished Professor. His research interests revolve around the chemistry of p-block elements and late transition metals with applications in the domain of molecular recognition, anion sensing and transport, and catalysis.

Webinar Content

On Tuesday, 2 November 2021, MDPI and the Journal Molecules organized the 20th webinar on Molecules, entitled "σ-Hole–Based Interactions: Halogen Bonds, Chalcogen Bonds and Beyond".

The introduction was held by the Chair of the webinar, Dr. Victor Mamane. He is a CNRS researcher at the University of Strasbourg. He graduated from Orsay University in 1998 and obtained his Ph.D. at the same university in 2001. In 2004, he was awarded the position of CNRS researcher at the University of Nancy, where he developed new methodologies in heterocyclic chemistry. In 2013, he moved to the University of Strasbourg, where he started a new project dedicated to the study of σ-hole interactions in solution and their application in catalysis. Currently, he is a member of the Organic Section Board of Molecules.

The first speaker to quick off this webinar was Prof. Dr. Antonio Frontera, with his presentation "Structure Guiding Role of σ-Hole Interactions in the Solid State". He is Full Professor of Organic Chemistry at the Universitat de les Illes Balears (UIB) and co-leader of the Supramolecular Chemistry research group, where he leads the Theoretical Chemistry Laboratory. His general research interests are focused on the study of noncovalent interactions, supramolecular chemistry, noncovalent catalysts, and crystal engineering. His current research interest is the study of σ/π-hole interactions.

The second presentation with the title "Halogen-Bonding in Catalysis" was held by Prof. Dr. Olga Garcia Mancheño. She is a professor of organic chemistry at the University of Münster (WWU). She obtained her Ph.D. in Chemistry in 2005 at the University Autonomous of Madrid under the supervision of Prof. J.C. Carretero.

Her research aims at developing new, efficient synthetic methodologies in organic chemistry, with a special focus on the design of novel catalytic systems and their application in homogenous catalysis, including photocatalysis, noncovalent interactions and asymmetric anion-binding catalysis.

The third presentation was held by Prof. Dr. François Gabbaï and its title was "Chalcogen and Pnictogen Bonding Augmented by the Charge and Redox State of the Main Group Element". In 1990 he joined the graduate program at the University of Texas at Austin. After obtaining his Ph.D. in 1994, he was awarded an Alexander von Humboldt Fellowship and subsequently a Marie Curie Fellowship. In 1998, he joined Texas A&M University, where he now holds the Arthur E. Martell Chair of Chemistry.
