Course objectives
The lecture is focused on the understanding and explanation of reactivity and properties of macrocylic compounds and it is accompanied by examples taken from literature or from experimental experiences of lecturer. In addition, the potential application of macrocyclic complexes in practice is mentioned.
Learning outcomes
Student understands and is able to explain the reactivity and properties of macrocylic compounds. He/she can ppropose the apllication of macrocyclic complexes in practice.
Syllabus
  • 1. Introduction into macrocylic chemistry (nomenclature, natural macrocyles, importance).
  • 2. Types of macrocylic ligands and their complexes, cyclic polyamines and porphyrines, cyclic polyethers (crowns, polyethers, cryptands, cavitands, calixarens), cyclic ligands with other donor atoms than O or N, polycore and polymer macrocycles, catenans and catenands, macrocyclic sugars, robust macrocycles, stereoisomerism of macrocycles, "hole-size" concept.
  • 3. Aspects of macrocycle synthesis. Free ligands - non-template synthesis, reaction of ring formation (synthesis under high and low dilution).
  • 4. Complexes - non-template synthesis, template synthesis (influence of physical and chemical conditions on kind and yield of reaction - kinds of template effects), in situ reactions. Derivatization of macrocycles - introduction of functional groups into cyclic skeleton and protection of cyclic skeleton.
  • 5. Chelate and macrocyclic effect - origin and quantification. Experimental techniques suitable for study of reactivity of macrocyclic compounds.
  • 6. Thermodynamic aspect - selectivity for ions. Kinetic aspect - formation and dissociation kinetics.
  • 7. Reactivity of complexes and their redox properties. Stabilisation of less common oxidation states - "metal-centered", "ligand-centered" oxidation and reduction. Substitution reactions in axial site, reaction of coordinated macrocyclic ligand, demetallic reactions and ionic exchange reactions.
  • 8. Macrocyclic systems. Complexation of metal ions (cyclic polyethers, polyamines and polyimines; cryptands, calixarenes, etc.).
  • 9. "Host-guest" chemistry - complexation of organic cations.
  • 10. Complexation of organic anions.
  • 11. Complexation of neutral compounds cyclodextrines.
  • 12. The use of macrocyclic ligands and their complexes in chemistry, biology, medicine - examples.
