Summary

Automatic Translation

Pålidelig, udarbejdelse af 1,2,3,4,5-pentamethylcyclopentadiene (Cp * H) mellemliggende skala præsenteres. Den reviderede protokol til syntese og oprensning af liganden minimerer behovet for specialiseret laboratorieudstyr samtidig forenkle reaktion workups og produkt rensning. Anvendelse af Cp * H ved syntesen af [Cp * MCL 2] 2 komplekser (M = Ru, Ir) er også beskrevet.
