  1. Issues in Inorganic Synthesis

  2. Ligand synthesis MeOH 20 h or so in NaOH pH ~11 Solvent : ethylene glycol

  3. Metallation of porphyrin Anything change at Fe? How do you know when the reaction is done? Porphyrin substituents on heme in hemoglobin

  4. Molybdenum Reactions. List them and conditions  MoOCl2detc2  Mo2O3detc4  MoOS2detc2  MoOdetc2

  5. Fe and Ru Reactions. List them and conditions FeCl(porphyrin)  Ru(bpy)2(L-pterin)

  6. Mechanism:

  8. from X-ray crystallography from Chem 3D; “guessed” structure What’s the difference between pictures A and B? A B

  9. X-ray Crystallography:the closest we can get to photographing our molecules! • single crystal (not a powder or many tiny crystals) • periodic array of atoms symmetrically oriented • produces accurate (almost) bond distances and bond angles • The method: • see U.Penn X-ray Facility • see on-line X-ray Course • see illustration of Space Group Symmetry • one of my old structures (on Cu)

  10. A single crystal structure of a Mo molecule from my lab:

  11. Who wants to go see it done?
