Description / Table of Contents:
coupling of a Fluoromethylidyne Ligand with Alkynes and Formation of a CF—CR—CR Ligand. Synthesis of Fe3(CO)8(μ3-CF)(μ3-CF—CR—CR)Nonacarbonyl-bis(μ3-fluoromethylidyne)triiron (4) reacts with alkynes R—C≡C—R (2a-e) and carbon-carbon bond formation to diferra-allyl clusters Fe3(CO)8(μ3-CF)(μ3-CF—CR—CR) (5a-e). The spectroscopic data of the compounds proof the existence of a μ3-fluoromethylidyne and a CF—CR—CR ligand in the molecules. The structure of Fe3(CO)8(μ3-CF)(μ3-CF—CH—CH) 5a is established by an X-ray crystal structure determination.
Notes:
Nonacarbonyl-bis(μ3-fluormethylidin)trieisen (4) reagiert mit Alkinen R—C≡C—R (2a-e), unter C—C-Bindungsknüpfung zu Diferra-Allyl-Clustern Fe3(CO)8(μ3-CF)(μ3-CF)(μ3-CF—CR—CR) (5a bis e). Die spektroskopischen Daten der Verbindungen belegen die Anwesenheit eines μ3-Fluormethylidin- und eines μ3-CF—CR—CR-Liganden. Die Struktur von Fe3(CO)8(μ3-CF)(μ3-CF—CH—CH) 5a wird durch eine Kristallstrukturuntersuchung gesichert.
