  1. Organometallic Chemistry. 2 Catalysis

  2. Organometallic Chemistry. The Players Introducing Wilkinson’s Catalyst, RhCl(PPh3)3

  3. Organometallic Chemistry. The Players Understanding Wilkinson’s Catalyst, RhCl(PPh3)3 Analyze electronic structure

  4. Organometallic Chemistry. The Players Understanding Wilkinson’s Catalyst, RhCl(PPh3)3 RhCl3(H2O)3 + excess PPh3 Analyze Reaction RhCl3(H2O)3 + 4 PPh3 RhCl3(PPh3)3+ O=PPh3 + 2 HCl + 2 H2O

  5. Organometallic Chemistry. The Players (Actually it’s more complicated…) RhCl3(H2O)3 + excess PPh3 heat Reaction Conditions?

  6. Organometallic Chemistry. The Play So what does Wilkinson’s catalyst do? Make a prediction?

  7. Organometallic Chemistry. The Plot

  8. Organometallic Chemistry. The Deception

  9. Organometallic Chemistry. Your play 1. Make the catalyst: RhCl3(H2O)3 + excess PPh3 2. Investigate this Reaction: heat ? + RCHO Mild heat Rh product ppts Filter; save filtrate Take IR and NMR of ppt ESI-MS of ppt Propose reaction

  10. Organometallic Chemistry. Next Week 1. Catalytic Olefin Hydrogenation 2. Analyze filtrate by GC-MS: does it confirm your proposed reaction?
