The module aims to introduce the student to advanced specialised topics of inorganic reaction mechanisms and organic synthesis.
This module covers inorganic reaction mechanisms and advanced organic synthesis with focus on asymmetric synthesis.
Keyword list (inorganic chemistry): Reaction Mechanisms. Classification of inorganic reaction mechanisms. What is a reaction mechanism? How are reaction mechanism studied? Kinetics. Reaction profiles for A, Ia Id and D mechanisms. Substitution at 4-coordinate transition-metal sites: Tetrahedral - Co-ordinatively saturated complexes (D mechanism); unsaturated complexes (A mechanism); competing mechanisms and temperature effects. Square-planar - Associative mechanisms and the role of solvent; evidence for a solvent intermediate; stereochemistry of substitution; influence of entering group (nucleophilicity scales); influence of spectator ligand (trans effect); influence of leaving group; dissociative mechanisms at square planar sites. Substitution at six-coordinate octahedral sites: role of solvent; the solvolysis reaction (leaving group; spectator ligands and stereochemistry); displacement of coordinated solvent (solvent exchange, inert/labile, CFAE, Eigen-Wilkins Id mechanism). Direct substitution without solvent interaction. Base catalysed hydrolysis (Dcb mechanism, tbp intermediate); acid catalysed hydrolysis; redox catalysed substitution. Electron-transfer reactions; classification of reactions: stoichiometry (complementary and noncomplementary reactions), mechanism (inner sphere and outer sphere); differentiation between inner and outer sphere reactions. Outer sphere reactions: self-exchange reactions and Marcus cross theory.
Organic section: This section of the module will revise and expand core concepts of selectivity and specificity, kinetic vs. thermodynamic control, regio- and stereo- control. Also, strategies and challenges in ring formation will be discussed. The material will be illustrated with examples of total synthesis, examined both from the synthetic, retrosynthetic and mechanistic perspective. A particular emphasis will be on diastereoselective and asymmetric synthesis (resolution, asymmetric induction, chiral auxiliary, chiral pool, organo catalysis, bio catalysis, asymmetric catalysis) in the view of both research and industrial applications.
