SUMMARY:Conférence du Professeur Ulrich Fekl (Toronto)
DESCRIPTION:Titre : Ligand-Based Reactivity of Metal Dithiolenes: Still G
 ood for Surprises.La conférence sera prononcée par le professeur Ulric
 h Fekl du département des sciences chimiques et physique de l'University
  of Toronto at Mississauga. Elle sera donnée en anglais.Résumé : A pro
 mising strategy for the formation of carbon-heteroatom bonds is the additi
 on of organic substrates to metal-bonded ligands. Such reactivity can be v
 ery pronounced at metal dithiolene complexes\, in particular if the reacti
 vity of the ligand is properly tuned by the choice of a 'spectator metal'.
  We have studied a variety of dithiolene complexes\, using nickel\, molybd
 enum and platinum. Such systems bind alkenes and/or 1\,3-dienes at the sul
 fur centers. We have produced chiral ligands by this method and have also 
 developed a catalytic cycle for dihydrobenzodithiin production by means of
  activation of bis-o-phenylene tetrasulfide. Furthermore\, ligand-based ch
 emistry leads to a new functional model for the enzyme DMSO reductase.Info
