DESCRIPTION:Titre : “Ca”-talysis: Homogeneous Catalysis with Organocalc
 ium Complexes.Endroit : Pavillon J.A.-Bombardier\, salle 1035 à 11 hHôte
  : Frank SchaperLa conférence sera prononcée (en anglais) par le profess
 eur Sjoerd Harder\, du département de chimie et de pharmacie de la Friedr
 ich-Alexander-Universität Erlangen-Nürnberg (Allemagne).Résumé : Decre
 asing oil reserves and increasing environmental awareness changed the focu
 s of chemical research dramatically. One of our main future challenges is 
 the conversion of renewable feedstocks by environmentally friendly\, safe 
 and cheap processes that are catalytic and energy- and atom-efficient and 
 generate useful and durable products.Although much thought has been put in
 to green processes using alternative feedstocks\, catalysts are often base
 d on classical transition metal species. However\, for a conversion to a d
 urable future chemistry we should also look into alternative catalysts tha
 t are based upon abundant\, cheap and non-toxic metals. In this context\, 
 organocalcium compounds have been reported as efficient catalysts for vari
 ous alkene conversions normally catalyzed by transition metals: e.g. polym
 erization\, hydroamination\, hydrosilylation\, hydrogenation or hydrophosp
 hination. This lecture gives an overview of selected examples in early mai
 n group metal catalysis and finishes with recent investigations on the wor
 king principles and the role of the metal. It will be shown that there is 
 only a thin line between “Ca”-talysis and Organocatalysis.Information
