Prof. Dr. Eva Hey-Hawkins (Universität Leipzig): Multifaceted Chemistry with Phosphorus-Functionalised Ferrocene Derivatives

AC Kolloquium
Referent/in: Prof. Dr. Eva Hey-Hawkins
Inhalt:

Cyclopentadienes with a P-functionalised alkyl or aryl side chain are useful precursors bifunctional ligands in main group and transition metal chemistry. We have developed two synthetic approaches for (chiral) phosphanylalkyl or -aryl cyclopentadienyl complexes: a) employing lithium salts, such as Li[(C5H4)-X-PR1R2] [R1 = H, alkyl, aryl; R2 = alkyl, aryl; X = alkylene, arylene, no bridge], as transfer reagents for the organic ligand, and b) by modification of the metal-bound cyclopentadienyl ring in ferrocenes.
Primary and secondary ferrocenyl phosphines, obtained by method b), display interesting reactivity and can be used as starting materials for further functionalisation of the phosphanyl group or for ferrocenyl-substituted P-B-based polymers.
Tertiary ferrocenyl phosphines, obtained by both methods, have many applications in catalytic reactions. The corresponding 1,1’-substituted ferrocenes can furthermore be used for immobilisation of the respective ferrocene derivatives, for example on dendrimers or other scaffolds.
Synthetic routes to these ferrocenyl phosphines, their properties and applications will be discussed.
