DESCRIPTION:Prof. Dr. Tanja Gulder\, Saarland University: \nHalogen Atoms 
 as Directing Tools: From Reactivity to Bioactive Compounds\n\nNature takes
  advantage of the beneficial properties of carbon-halogen (C\,X) bonds and
  uses them as a strategic tool for assembling structurally complex framewo
 rks. Likewise\, installing a halogen atom in organic synthesis opens furth
 er transformations\, particularly carbon-carbon (C\,C) forming reactions. 
 By harnessing the concept of cryptic halogenations using hypervalent iodan
 e chemistry\, electrochemistry\, or combining enzyme and chemocatalysis\, 
 efficient multi-step sequences are performed in a straightforward way. In 
 addition\, our group utilizes fluorinated Lewis acid-Lewis base cooperativ
 e effects\, thus steering transformations\, such as terpene cyclizations\,
  and activating strong bonds\, e.g.\, for hydrogen isotope exchange\, by c
 reating dynamic and catalytically active supramolecular assemblies in solu
 tion.
