Reaction chemistry of organometallic Compounds

Three general forms:

1- Reactions involving the gain and loss of ligands

  • Ligand Dissoc. and Assoc. (Bala)
  • Oxidative Addition
  • Reductive Elimination
  • Nucleophillic displacement

 

2- Reactions involving modifications of the ligand 

  • Insertion
  • Carbonyl insertion (alkyl migration)
  • Hydride elimination (equilibrium)

 

  1. Catalytic processes by the complexes

   Wilkinson, Monsanto

  Carbon-carbon bond formation (Heck etc.)
