“…Recent results12 indicate that [{Cp′′′Fe} 2 (μ,η 1:1 ‐P 1 )(μ,η 3:3 ‐P 3 )] could be an intermediate in this reaction and that it undergoes further fragmentation and reaggregation under harsh thermolytic conditions. The formation of a P 3 ‐containing fragment was postulated earlier by Scherer and co‐workers, who observed the formation of [Cp′′′Fe(η 5 ‐P 3 C 2 Ph 2 )] during the co‐thermolysis of 1 with the acetylene derivative C 2 Ph 2 13. To obtain mixed E 4 and cyclo ‐E 5 ligand complexes, 1 was treated with yellow arsenic in boiling decalin until the carbonyl bands of 1 disappeared from the IR spectrum [Eq.…”

“…Whereas the ferrocenes of type B 7 as well as B′ and C′ 8 were synthesized later using phosphaalkyne as starting material for B′ and C′ , the missing 1,2,3‐triphosphaferrocene C was only recently synthesized by Scherer et al by the reaction of the tetraphosphabicyclobutadiene complex 1 with diphenylacetylene 9. In the series shown, the hitherto missing complex D is of interest for us, since our general goal lies in the use of P n ligand complexes as linking units for the formation of soluble supramolecular aggregates10 as well as 1D and 2D polymers and networks 11.…”

“…Während Komplex 51 mit P 4 -Butterflygerüst (Abbildung 18) nicht rein isoliert werden konnte, lässt sich exo/exo-[{Cp R (OC) 2 -Fe} 2 (µ-η 1 :η 1 -P 4 )] (33) durch Kurzzeitthermolyse (110°C, 2 min) von [{Cp R (OC) 2 Fe} 2 ] und P 4 in 75 % Ausbeute synthetisieren und durch eine Röntgenstrukturanalyse charakterisieren [21]. Erste Experimente zeigen, dass 33 selbst als vielversprechende P n -Quelle für neue phosphorhaltige Moleküle geeignet ist.…”

“…Im Gegensatz zu den gut untersuchten Sandwichkomplexen mit einem 1,2,4-Triphospholylliganden (G in Abbildung 19) ist das wenig erforschte 1,2,3-Triphospholyl-Isomere H [12] jetzt relativ einfach zugänglich und im Metallocenderivat 56 durch eine Kristallstrukturanalyse, die keine Besonderheiten aufweist, charakterisiert [21]. Mit der Synthese von 56 ist ein wichtiger, gezielter Brückenschlag zur Organischen Chemie geglückt [12].…”
