SUMMARY:Séminaire - Candidat Professeur - Peter E. Sues
DESCRIPTION:Titre : “Using Ligand Design and Mechanistic Investigations t
 o Develop Catalysts for Asymmetric Hydrogenation and Olefin Metathesis''En
 droit : Pavillon Roger-Gaudry\, salle G-715 à 11 h 00.
\nCette confér
 ence sera prononcée par Peter E. Sues\, Ph.D. du Massachusetts Institu
 te of Technology\, postdoctorant sous la supervision du Professeur Richar
 d R. Schrock.
\nRésumé : The asymmetric hydrogenation (AH) of polar doub
 le bonds is an important process that is used by the pharmaceutical\, perf
 ume\, and food industries in the synthesis of enantiopure alcohols and ami
 nes. Traditionally\, platinum metal-based catalysts are used to catalyze t
 hese reactions on the industrial scale. This presentation will explore alt
 ernative iron(II) carbonyl systems with multidentate ligands\, which are h
 ighly active and selective in the AH of prochiral ketones. Using experimen
 tal and computational methods\, the mechanism of action of these systems\,
  and their decomposition pathways will be discussed\, along with a rutheni
 um half-sandwich complex capable of activating dioxygen. In addition\, the
  development of olefin metathesis (OM) catalysts in the context of alkane 
 metathesis (AM)\, a process for generating diesel fuels from biomass\, wil
 l also be presented. Strategies to design systems stable at high temperatu
 res will be discussed\, as will mechanistic insights into the decompositio
 n pathways of OM catalysts at high temperatures. Lastly\, the synthesis of
  heterogeneous OM catalysts will be outlined\, and their activities for bo
 th OM and AM will be presented.
