The chemical industry is an enabling industry. Chemicals are supplied to almost every other industry. The manufacture of ​goods from oil, coal or gas to ​everyday consumer products comprises in more or less all cases at least one catalytic step. Catalysis in truly multidisciplinary with respect to various areas: inorganic chemistry, organic chemistry, biochemistry, chemical engineering, extra. As industry becomes more oriented toward specialty chemicals, methods to catalyse functional group transformations, hydrocarbon activation, polymerisations, inductions of asymmetry and recently photo-activation chemistry will be increasingly in demand. The transition metals complexes have provided a series of important conceptual insights, surprising structures and useful catalysts both for industrial processes, for organic synthesis and for the energy conversion. Today, many catalysts are capable of very high levels of asymmetric induction in preferentially forming one enantiomer of a chiral product. This field is very interesting for the pharmaceutical industries. Recently, the transition metals complexes have been showed an important catalytic activity to convert the natural energy (water, light) to a chemical energy. These types of molecules were used in the human health domain as

 important anti-cancer drugs.The seminar will focus primarily on 1) the synthesis of new transition cyclometalated complexes (palladacycles, iridacycles and ruthenacycles) with planar chirality by C-H activation, 2)  the development of new efficient catalysts which are able to catalyze the hydroamination of alkynes and hydrosilylation of imines in one-pot reaction at room temperature, 3) the water splitting catalysis, 4) the development of new "eco-aware" catalysts for the photocatalytic oxidation of organic substrates by dioxygen activation using Ru/Cu complexes as catalysts and 5) on  the development of new thematic which is SABRE: Signal Amplification By Reversible Exchange which has the role to increase the sensitivity of the MRI.

 

 

At 2009 Dr. Wissam, did a Master degree in Molecular and Supramolecular Chemistry at the University of Strasbourg, France. On September 2009, He started his Ph.D for 3 years at the University of Strasbourg, essentially based on organometallic chemistry and catalysis. At the University of Strasbourg, He plays the role of non-permanent assistant professor for 2 years. He taught the organic, inorganic and general chemistry for the undergraduate students. December 2012, He started his first postdoctoral position for 2 years at the Commission of Atomic Energy and Alternative Energies of France (CEA-Grenoble) to develop a new project entitled photocatalytic oxidation of organic substrates by Ru/Cu hetero-metallic complexes via dioxygen activation. Between 09-2013 and 12-2014, He worked at Joseph Fourier University as non-permanent assistant professor where he taught the chemistry for the undergraduate students. Actually, he is working as research associate at the center for hyperpolarisation in magnetic resonance of the University of York, UK. He is also developing new catalysts for SABRE (Signal Amplification By 

Reversible Exchange) discovered by Prof. Simon Duckett on 2009 at the University of York.
