What Is Metathesis Of Compounds

Olefin metathesis is a chemical reaction in which two carbon-carbon double bonds (olefins) come together and exchange with one another, forming new olefinic products in the process.

Some decomposition reactions are Disproportion Reactions.

Metathesis reaction is a type of, which include combination, decomposition, anddisplacement.

Janusz Lewiński was born in 1956 in Poland. He did his undergraduate and doctoral studies at Warsaw University of Technology, and received Ph.D. degree in 1989 under the supervision of Professor S. Pasynkiewicz. Then he joined the Department of Homogeneous Catalysis and Organometallics at the same University, where he first developed his interest in organometallic chemistry, in particular the chemistry of the group 13 elements, and helped to pioneer the 27Al NMR spectroscopy in the identification of aluminium complexes. In 2001 he completed habilitation, and in 2007 he was appointed full professor at Warsaw University of Technology, where he is now Head of Organometallic and Functional Materials Laboratory. In 2007 accepted a similar position at the Institute of Physical Chemistry of Polish Academy of Science.

He spent periods as a visiting scientist and lecturer at the University van Amsterdam (Host: Prof. G. van Koten and Prof D. J. Stufkens), the Rice University, Houston (Host: Prof. A. R. Barron), and the Cambridge University (Host: Prof. A. E. H. Wheathley). His awards include, amongst others, the 2000 Polish Chemical Society′s Kemula Prize and the 2008 Sklodowska-Curie Award of Polish Academy of Science for his scientific activity in the field of organometallic chemistry.

His research addresses fundamental and applied aspects of the main group metals chemistry and is aimed at understanding the relationships between the structure, reactivity and desired functionality of various entities. He made seminal advances in the understanding of the reactivity of metal-carbon bonds in the group 12 and 13 organometallics, probing their activation of dioxygen. Aside from any fundamental curiosity concerning the structure characterization of the first aluminium and zinc alkylperoxides, a hypothesis concerning the reaction mechanism of metal alkyls with O2 was significantly advanced. His group revealed also a long overlooked decomposition pathway of zinc alkylperoxides via homolysis of the O-O bond which is responsible for the formation of oxo complexes. In this connection, he has also invented novel and efficient routes to polymer-coated zinc oxide nanoparticles for biomedical applications.

His other topics of research concern the field of supramolecular chemistry, crystal engineering and fabrication of hybrid organic–inorganic functional materials like coordination polymers based on organometallic nodes or open metal–organic frameworks with controllable size and morphology with potential applications in storage and separation of gases and small organic molecules.

Professor Prakash’s mechanistic studies include isolation and characterization by low temperature NMR of reactive intermediates such as carbocations, heterocations, onium ions, onium ylides and carbanions. His achievements include solving the structure of the highly controversial nonclassical 2-norbornyl cation, pagodane and isopagodane dications. The pagodane and isopagodane dications are the first examples of frozen Woodward-Hoffmann transition state analogs. His prolific studies on electron deficient intermediates are of fundamental importance in understanding strong acid catalyzed hydrocarbon conversion processes.
